The mail or post is a system for physically transporting postcards, letters, and parcels. A postal service can be private or public, though many governments place restrictions on private systems. Since the mid-19th century, national postal systems have generally been established as a government monopoly, with a fee on the article prepaid. Proof of payment is usually in the form of an adhesive postage stamp, but a postage meter is also used for bulk mailing.
A postcard or post card is a piece of thick paper or thin cardboard, typically rectangular, intended for writing and mailing without an envelope. Non-rectangular shapes may also be used but are rare.
Mail art, also known as postal art and correspondence art, is an artistic movement centered on sending small-scale works through the postal service. It developed out of what eventually became Ray Johnson's New York Correspondence School and the Fluxus movements of the 1960s. It has since developed into a global, ongoing movement.
The Private Express Statutes (PES) are a group of United States federal civil and criminal laws placing various restrictions on the carriage and delivery of letters by all organizations other than the United States Postal Service.
Postal history is the study of postal systems and how they operate and, or, the study of the use of postage stamps and covers and associated postal artifacts illustrating historical episodes in the development of postal systems. The term is attributed to Robson Lowe, a professional philatelist, stamp dealer and stamp auctioneer, who made the first organised study of the subject in the 1930s and described philatelists as "students of science", but postal historians as "students of humanity". More precisely, philatelists describe postal history as the study of rates, routes, markings, and means.
Airmail is a mail transport service branded and sold on the basis of at least one leg of its journey being by air. Airmail items typically arrive more quickly than surface mail, and usually cost more to send. Airmail may be the only option for sending mail to some destinations, such as overseas, if the mail cannot wait the time it would take to arrive by ship, sometimes weeks. The Universal Postal Union adopted comprehensive rules for airmail at its 1929 Postal Union Congress in London. Since the official language of the Universal Postal Union is French, airmail items worldwide are often marked Par avion, literally: "by airplane".
An airmail stamp is a postage stamp intended to pay either an airmail fee that is charged in addition to the surface rate, or the full airmail rate, for an item of mail to be transported by air.
Registered mail is a mail service offered by postal services in many countries which allows the sender proof of mailing via a mailing receipt and, upon request, electronic verification that an article was delivered or that a delivery attempt was made. Depending on the country, additional services may also be available, such as:
In aeronautics, a balloon is an unpowered aerostat, which remains aloft or floats due to its buoyancy. A balloon may be free, moving with the wind, or tethered to a fixed point. It is distinct from an airship, which is a powered aerostat that can propel itself through the air in a controlled manner.
A gas balloon is a balloon that rises and floats in the air because it is filled with a gas lighter than air. When not in flight, it is tethered to prevent it from flying away and is sealed at the bottom to prevent the escape of gas. A gas balloon may also be called a Charlière for its inventor, the Frenchman Jacques Charles. Today, familiar gas balloons include large blimps and small latex party balloons. For nearly 200 years, well into the 20th century, manned balloon flight utilized gas balloons before hot-air balloons became dominant. Without power, heat or fuel, untethered flights of gas balloons depended on the skill of the pilot. Gas balloons have greater lift for a given volume, so they do not need to be so large, and they can stay up for much longer than hot air balloons.
The National Committee for a Free Europe, later known as Free Europe Committee, was an anti-communist Central Intelligence Agency (CIA) front organization, founded on June 1, 1949, in New York City, which worked for the spreading of NATO influence in Eastern Europe and to covertly destabilize Soviet Bloc countries.
Freepost is a postal service provided by various postal administrations, whereby a person sends mail without affixing postage, and the recipient pays the postage when collecting the mail. Freepost differs from self-addressed stamped envelopes, courtesy reply mail, and metered reply mail in that the recipient of the freepost pays only for those items that are actually received, rather than for all that are distributed. Freepost of preprinted cards issued by businesses is also different from postal stationery sold by postal administrations.
Airborne leaflet propaganda is a form of psychological warfare in which leaflets (flyers) are scattered in the air.
Pigeon post is the use of homing pigeons to carry messages. Pigeons are effective as messengers due to their natural homing abilities. The pigeons are transported to a destination in cages, where they are attached with messages, then the pigeon naturally flies back to its home where the recipient could read the message. They have been used in many places around the world. Pigeons have also been used to great effect in military situations, and are in this case referred to as war pigeons.
Les Frères Robert were two French brothers. Anne-Jean Robert (1758–1820) and Nicolas-Louis Robert (1760–1820) were the engineers who built the world's first hydrogen balloon for professor Jacques Charles, which flew from central Paris on 27 August 1783. They went on to build the world's first manned hydrogen balloon, and on 1 December 1783 Nicolas-Louis accompanied Jacques Charles on a 2-hour, 5-minute flight. Their barometer and thermometer made it the first balloon flight to provide meteorological measurements of the atmosphere above the Earth's surface.
A flyer is a form of paper advertisement intended for wide distribution and typically posted or distributed in a public place, handed out to individuals or sent through the mail. Today, flyers range from inexpensively photocopied leaflets to expensive, glossy, full-color circulars. Flyers in a digital format can be shared on the internet.
Gérard Lhéritier is a French manuscript dealer and expert in balloon mail. He is a sponsor of the National Library of France and around 2004 was the buyer of the manuscript of the Marquis de Sade’s 120 Days of Sodom. In 1990 he founded Aristophil but in March 2015, was arrested by French police in connection with an investigation into a suspected pyramid scheme fraud at the firm. In 2012, he won the largest ever EuroMillions jackpot awarded in France at €170 million.
Balloon propaganda campaigns in Korea include both North and South Korean propaganda leaflet campaigns through the use of balloons as a distribution method since the Korean War. A variety of other contents have also been included with the balloons. Originally, these campaigns were organized by the governments and militaries of the Korean states. Contemporarily, however, they are mainly organized by South Korean non-governmental organizations (NGOs) that regularly involve themselves in balloon release events that aim to send materials censored in North Korea, as well as various other goods, to the North Korean people.
A Boule de Moulins was a method of transporting mail from the provinces to the city of Paris, used during the siege of the 1870 war. As the mail to be transported in this way in hollow spheres is first centralized in Moulins (Allier), these balls are called "de Moulins".
