How’s this for rare and historically significant: a Pete Rose and Bart Giamatti signed 1983 All-Star Game First-Day Cover?!
If you weren’t aware:
Giamatti served as Commissioner for only five months before dying suddenly of a heart attack. He is the shortest-tenured baseball commissioner in the sport’s history and the only holder of the office not to preside over a full Major League Baseball season. Giamatti’s most notable act as Commissioner was to negotiate the agreement resolving the Pete Rose betting scandal in which Rose was permitted to voluntarily withdraw from the sport to avoid further punishment.
