I came across a good deal at Joann Fabrics. A baseball card display that holds 20 cards. I only have about 50 signed cards and was going to fill it with a combination of baseball, basketball, and football cards. I decided to use it only for my baseball cards.
My goal is to eventually fill it with nothing but signed L.A. Dodger cards. Walmart has a similar one linked here. The pic is a lot better than mine in case you want to take a better look at it. The card display measures 16X20 inches. It features 20 snap tight card holders that make it easy to install or remove cards. It is also easy to mount onto the wall. Once it is mounted to the wall it looks very nice.
