My dad had an absolute ton of aircraft memorabilia. I wish I didn't know any better and could just heave this stuff. You name it, he's got three of it. The hardcover books alone could easily equip a base library. Insane. Unopened boxes of mahogany models from The Phillipines. Impact resistant models of aircraft usually handed out by the companies that build them, and displayed on the desks of guys that drive them.
Oddball handouts and press releases from the late 40's through the 50's by companies like Grumman, Republic, North American, Convair (Consolidated Vultee). Literally tons of that stuff.
