Found this old poster, it looks like it was copyrighted by Smith and Wesson in 1944 on the lower left corner. I have never seen this one or even a copy of it. All the guns on it are pre-war and has the 357 magnum on it, but does not distinguish "Registered" as part of the magnum. I like it a bunch even though it is a little tattered, but for a 70 year old poster it is not too bad. Even the wife likes it...
Specifically, it lists 19 different models and has about 9 different colors on the poster, also has metal banding at the top and the bottom. It is 23" wide x 37.5" length. Very interesting to look at and I can put some pictures of the specific guns are details of the poster on here if you want. Maybe there is a better example on the forum somewhere?
