Stamp Philip Mazzei (1730-1816), Italian-born Political Writer it reflects the thematic directions:

An aircraft (pl. aircraft) is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or the dynamic lift of an airfoil, or, in a few cases, direct downward thrust from its engines. Common examples of aircraft include airplanes, rotorcraft (including helicopters), airships (including blimps), gliders, paramotors, and hot air balloons.Part 1 (Definitions and Abbreviations) of Subchapter A of Chapter I of Title 14 of the U. S. Code of Federal Regulations states that aircraft "means a device that is used or intended to be used for flight in the air."

In legal discourse, an author is the creator of an original work, whether that work is in written, graphic, or recorded medium. The creation of such a work is an act of authorship. Thus, a sculptor, painter, or composer, is an author of their respective sculptures, paintings, or compositions, even though in common parlance, an author is often thought of as the writer of a book, article, play, or other written work.In the case of a work for hire, the employer or commissioning party is considered the author of the work, even if they did not write or otherwise create the work, but merely instructed another individual to do so.

Aviation is the practical aspect or art of aeronautics, being the design, development, production, operation and use of aircraft, especially heavier than air aircraft. The word aviation was coined by French writer and former naval officer Gabriel La Landelle in 1863, from the verb avier (synonymous flying), itself derived from the Latin word avis ("bird") and the suffix -ation.

Famous People refers to the fame and public attention accorded by the mass media to individuals or groups or, occasionally, animals, but is usually applied to the persons or groups of people (celebrity couples, families, etc.) themselves who receive such a status of fame and attention. Celebrity status is often associated with wealth (commonly referred to as fame and fortune), while fame often provides opportunities to make money.

A joint issue is the release of stamps or postal stationery by two or more countries to commemorate the same topic, event or person. Joint issues typically have the same first day of issue and their design is often similar or identical, except for the identification of country and value.
