Creative Cardboard Concepts have released Famous Fabrics, a set that spans many sports from MLB - MMA. Every card in the set is autographed or game used, and is serial numbered to 9 or less.
Only 400 Cases were produced, and the list of names in the set is impressive. Jordan, Gretzky, and cut autographs of Babe Ruth and Honus Wagner are among the hits.
