2008 Topps Co-Signers Baseball. The new version of Topps' autograph-heavy set will feature signatures from over 30 boxers - including current champions like Kelly Pavlik and Juan Diaz and former stars like Ray "Boom Boom" Mancini and Thomas Hearns. And since it's Co-Signers, there will also be double, triple and quad autograph cards.

These cards are due to be released sometime in May.
