To celebrate the 40th anniversary of the only All Star Game held at Memorial Stadium, Bulls Eye Cachets produced commemorative postmarked cachets in 1998.
I had two cachets signed by the only two Orioles who had made the A.L. All Star squad that season, catcher Gus Triandos & pitcher Billy O'Dell who retired all of the nine batters he faced (which included five future Hall of Famers), to help preserve a 4-3 A.L. victory.
