I strongly suspect that the memo purportedly written by General Hoyt S. Vandenberg in 1944 featured in the Showcase section on p. 18 is a hoax.
The "signature" of General Vandenberg is completely unlike genuine signatures on a document and photo offered by auction houses on the internet.
My suspicions were aroused by the memo itself. Military competitions are concerned with military skills, not appearances. The idea of a "competiton" which would emphasize weathered aircraft seemed pretty bogus right from the start. If such a competition ever really existed, there should be plenty of records available in unit histories [I have not looked; please feel free to prove me wrong]. FineScale Modeler should have done some more research before publishing this memo.
