A decade before breaking baseball's color barrier, Jackie Robinson was already making a name for himself during his freshman season at Pasadena Junior College. Offered is the 1937 edition of "Campus" signed neatly by the teenage "Jack Robinson" over his baseball photo in blue fountain pen. This very well may be the earliest Jackie Robinson signed baseball image extant. Amongst the hundreds of other signatures in the yearbook, is that of Mack Robinson, Jackie's older brother and silver medalist in the 1936 Olympics. The autograph is a "10", and the very delicate spiral bound yearbook is in overall EX-MT condition.
