During the mid-19th century in the United States, baseball and photography were both gaining popularity. As a result, baseball clubs began to pose for group and individual pictures, much like members of other clubs and associations posed. Some of these photographs were printed onto small cards similar to modern wallet photos. As baseball increased in popularity and became a professional sport during the late 1860s, trade cards featuring baseball players appeared. These were used by a variety of companies to promote their business, even if the products being advertised had no connection with baseball. In 1868, Peck and Snyder, a sporting goods store in New York, began producing trade cards featuring baseball teams. Peck and Snyder sold baseball equipment, and the cards were a natural advertising vehicle. The Peck and Snyder cards are sometimes considered the first baseball cards.
