A postage stamp is a small piece of paper issued by a post office, postal administration, or other authorized vendors to customers who pay postage. Then the stamp is affixed to the face or address-side of any item of mail—an envelope or other postal cover —which they wish to send. The item is then processed by the postal system, where a postmark or cancellation mark—in modern usage indicating date and point of origin of mailing—is applied to the stamp and its left and right sides to prevent its reuse. Next the item is delivered to its addressee.
Stamp collecting is the collecting of postage stamps and related objects. It is an area of philately, which is the study of stamps. It has been one of the world's most popular hobbies since the late nineteenth century with the rapid growth of the postal service, as a never-ending stream of new stamps was produced by countries that sought to advertise their distinctiveness through their stamps.
A cancellation is a postal marking applied on a postage stamp or postal stationery to deface the stamp and to prevent its reuse. Cancellations come in a huge variety of designs, shapes, sizes, and colors. Modern cancellations commonly include the date and post office location where the stamps were mailed, in addition to lines or bars designed to cover the stamp itself. The term "postmark" refers specifically to the part that contains the date and posting location, but the term is often used interchangeably with "cancellation" as it may serve that purpose. The portion of a cancellation that is designed to deface the stamp and does not contain writing is also called the "obliteration" or killer. Some stamps are issued pre-cancelled with a printed or stamped cancellation and do not need to have a cancellation added. Cancellations can affect the value of stamps to collectors, positively or negatively. Cancellations of some countries have been extensively studied by philatelists, and many stamp collectors and postal history collectors collect cancellations in addition to the stamps themselves.

The Mexican postal system has its roots in the Aztec system of messengers which the Spanish adopted after the Conquest. A postal service was established in 1580, mainly to communicate between the viceroyalty of New Spain with the motherland Spain. During the 18th century, Spain established a formal postal system with regular routes. In 1856, Mexico issued its first adhesive postage stamps, with "district overprints", a unique feature among postal systems worldwide, employed to protect from theft of postage stamps.

The Ottoman Empire became the Republic of Turkey in 1923, and in the following years, its postal service became more modernized and efficient and its postage stamps expertly designed and manufactured.

The Washington–Franklin Issues are a series of definitive U.S. Postage stamps depicting George Washington and Benjamin Franklin, issued by the U.S. Post Office between 1908 and 1922. The distinctive feature of this issue is that it employs only two engraved heads set in ovals—Washington and Franklin in full profile—and replicates one or another of these portraits on every stamp denomination in the series. This is a significant departure from previous definitive issues, which had featured pantheons of famous Americans, with each portrait-image confined to a single denomination. At the same time, this break with the recent past represented a return to origins. Washington and Franklin, after all, had appeared on the first two American stamps, issued in 1847, and during the next fifteen years, each of the eight stamp denominations available featured either Washington or Franklin.
