You can find this Poster on the Internet, offered as original, for $300+ (see my last posted photo for an example). However, it has been determined that this Poster design "appeared" on the market in the early 70's and is based on a WW2 era German magazine ad.

Silkscreened in black on a heavy silver paper stock (Looks at a glance like an aluminum lithographic plate). Traditional silkscreen - there is no dot pattern. In my collection since the early 70's - Not a modern inkjet copy. Ships rolled (US only).
