Baseball cards have been around a lot longer than most people think. Since the 1870s companies used baseball cards to help sell their products. And they all weren’t found in just bubble gum packs either. They were used a lot to sell cigarettes. Baseball cards weren’t included in bubble gum packs until the 1950s when Topps started the tradition. Cards were used to sell a lot of different items including beer, dog food, cheese, and even underwear! This is a great page to find some of these great collectible baseball cards.
