We know their autographs weren't juiced. Back when Jose Canseco and Mark McGwire were the feared Bash Brothers, they signed all six of these game-issue, officially stamped balls from the 1990 World Series, along with their A's teammates. Manager Tony LaRussa signed in the same place on all six, where the seams curve closest together. Carney Lansford gets style points and Rickey Henderson sort of blends in -- something that never happened on the field. The sting of being swept by the Reds might have faded, but these balls are fresh and will stay that way in their lucite boxes. Overall EX-MT.
