In this collection are the following aircraft posters (using the MacArthur naming convention): BettyDaveDinahEmilyHampJakeKateLilyMavisNateNellOscarRufeSallyTonyVal-IIZero Each poster provides the silhouettes, dimensions, and relevant information to educate both air and ground personnel in aircraft identification. Immediate identification of aircraft, friend vs foe, 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 only report). These posters have been linked to a US Navy procurement order of "GPO Order 11174, Req No 3912, and Jacket No 572602" from an earlier reference.  We have been unable to link this information to other US Navy documentat
