Fleer was prevented from using current players by Topps' exclusive rights, so they issued their Baseball Greats set using retired players, managers, executives and the two league commissioners. Luckily Fleer had their own exclusive rights deal with Ted Williams, who quickly became the most in demand card in the set.

Unfortunately the weak card design and retired players made it a giant dud with kids and the product was not well received.
Cards were sold in five-cent packs and packaged with two special inserts; a logo team decal and team pennant sticker of past World Series champions.
