Here's another way to try it, Oleg:
1. The solder in pre-WWII US Army dress.
2. Two rifles: a) 1903 Springfield, and b) sporterized Springfield--this one with good wood, scope, etc. etc.
Do variants on this--Garand, sporterized Garand, M-16 / Colt Sporter, etc.
Dress the soldier as appropriate--WWII / Korean War, Viet Nam, Gulf, etc., etc. Work on the earliest ones first.
The one most relevant for today's "hunters" might well be the Remington 700, etc.--the military model and the sports model, of course.
Finally, find the EXACT QUOTE WE NEED from the Brady Bunch, Josh Sugarman, whoever, and use that, c/w reference to the original context in fine print. IMO, it must be one about "high-powered" sniper rifles, and the context in which it was originally made by the gun-grabber should refer to the rifle used in this poster.
Some of us will help you find the quote, I'm sure.
Set this up so it can be printed in a standard photo printer--and can be made into a 24x36 poster.
Version TWO: do this with shotguns.
