This original ‘RESTRICTED’ aircraft identification poster was published by the U.S. Naval Aviation Training Division Feb 1944. This poster was posted as a training tool as well as an in theater ID poster to help U.S. and other Allied pilots, bomber crews and Naval personal to identify Allied and enemy aircraft. W.E.F.T.U.P. or Wing, Engine, Fuselage, Tail, Undercarriage, Peculiarities was a system set up for the purpose of aircraft identification and recognition.

World War II saw some of the first introduction of these aircraft ID poster to prevent friendly fire and more accurate plane recognition in combat. It was believed these posters alone could save countless lives from friendly aircraft-on-aircraft or friendly anit-aircraft fire. These posters also could cut down precious second pilots, bomber gunners, and naval gun crews would have to ID a plane flying towards them intern saving their lives by shooting first.

Each poster provides the silhouettes, dimensions, and relevant information to educate both air and ground personnel in aircraft identification. Immediate identification of aircraft, friendly or not, was essential in order for the observer (whether in the air e.g., pilot, gunner, or patrol observer, or on the ground, e.g., anti-aircraft crew) to determine his next course of action (e.g., acknowledge, attack, evade, or report). Each poster details a large clean sky and background image of the specified aircraft located as the main top imagine on the poster. It also contains important ‘peculiarities’ such as where certain gun emplacements are located, other special aircraft features, as well as wing and length measurements.

The Yakovlev Yak-1 (Russian: Яковлев Як-1) was a Soviet fighter aircraft of World War II. The Yak-1 was a single-seat monoplane with a composite structure and wooden wings; production began in early 1940.[1]The Yak-1 was a manoeuvrable, fast and competitive fighter aircraft. The composite-wooden structure made it easy to maintain and the engine proved to be reliable. It formed the basis for subsequent developments from the Yakovlev bureau. It was the founder of a family of aircraft, with some 43,000 being built.[4][5] As a reward, designer Alexander Yakovlev was awarded the Order of Lenin (Russian Орден Ленина, Orden Lenina) (the highest civilian decoration bestowed by the Soviet Union), a 100,000 ruble prize, and a ZIS motor car.
