Funny...when I worked at S&W in 78+9 I never noticed the original paintings !! What I can tell you is the "older" prints have more vivid colors and seem to be harder to acquire on line now. After a while the comparison becomes more obvious. One to keep your eye out for is "The Last Cartridge" that has a "little bear" in it that mom is protecting. Definitely and older print and HTF. I believe my 1st wife has one. When she cleaned me out she took my beautiful prints that were gifts from a fellow employee. I believe currently on E-bay there is a print of "The Hostiles" from the 50's for sale from an Australian seller. The older ones are worth tracking down. The ones I now have WILL NOT be snatched from me !! Good luck on the hunt !
