Fleer became known as a maker of sports cards, and also produced some non-sports trading cards. In 1992, Fleer was sold to Marvel Entertainment Group. SkyBox International also produced many licensed non-sports trading cards in the early 1990’s and in 1995 was acquired by Fleer. Fleer/Skybox produced a large number of both sports and non-sports cards in the mid 1990’s and early 2000’s. In 2005 Fleer suspended its trading card operation and Upper Deck bought the Fleer name in an auction.
