Up to four variations per card are presently accounted for. These variations are in the sepia overlay. Cards were printed in black and white and the sepia overlay is where the variation is. Early cards of Fred McMullin (Only known card during his career), Swede Risberg, Lefty Williams and "Sleepy" Bill Burns are in this set. All four of those people had roles in the Black Sox Scandal of 1919. These cards measure approximately 2 by 3 3/4".
