In June of 1991, Perelman announced that Marvel would sell its stock to the public for the first time. Perelman pushed Marvel to expand into other areas with the 1992 purchase of Fleer Corporation, which made trading cards, and the 1993 exchange of a 46% interest in Toy Biz, a toy company owned by Isaac Perlmutter, in return for the use of Marvel’s characters. Throughout the early nineties, Marvel completed a number of acquisitions, including children’s kites (Sepctra Star), stickers (Panini), toy rockets (Quest), smaller publishers (Welsh Publishing and Malibu Comics), another trading card company (SkyBox), and a distribution operation (Superhero Enterprises).
