jamieheres the link on the old cardboard website about the set:
http://www.oldcardboard.com/o/stamps/1912-bb/1912-bb.asp?cardsetID=1195
only 4 known players- looks like mathewson is the 5th. doesnt look like theres a lot known about the set- who released it, when, and how- or i probably wouldve thrown a higher bid out there
