ARCADE CARD Tex Ritter, Gene Autry, Lone Ranger

I have up for bids a picture of 3 different TV Stars from the 1950's era. Bought these at an Estate sale 3 weeks ago. I bought these because I thought they were different. I collect Cap Guns from the 1940-50 era. These look like the Arcade Cards that you find on eBay. I was told that this is like the One's that were displayed in the Movie Theater's back in the 1950's, not sure if this is true or not. Someone that collects this sort of stuff should know. The pictures are of Tex Ritter, Gene Autry & Lone Ranger. The 3 pictures are glued on heavy Black Cardboard. The pictures measure approx. 3 3/8"x 5 3/8". On the pictures it is stamped Made in U.S.A. On the bottom it says "The Exhibit Supply Co. Chicago". The pictures are signed . Buyer to pay $3.80 for Handling, Shipping and Delivery Confirmation within the USA.
