Fleer Corporation was an American company known for producing sports trading cards and collectibles. Founded in 1885, it became a prominent name in the trading card industry, especially during the 1980s and 1990s. The company was recognized for its innovative designs and high-quality products, including cards featuring popular sports like baseball, basketball, and football. In 1992, Fleer was acquired by Upper Deck Company, which further expanded its reach in the collectibles market. Despite its initial success, Fleer faced challenges in the competitive trading card industry and eventually ceased operations in 2005. Today, Fleer cards remain popular among collectors and sports enthusiasts.
