Without a doubt the most important issuer of boxing cards was the Chicago-based Exhibit Supply Company. Beginning with its inaugural issue of 1921 and continuing until about 1971 when its last boxing cards were printed, the Exhibit Supply Company, or “ESCO” as its diamond-shaped logo said, was the unparalleled card manufacturer/chronicler of boxers.  From a long-time boxing collector comes this nice assembly of Exhibit boxers.  With many years represented, this collection of 104 cards features boxing stars such as Louis, Robinson, Graziano, Liston and others.  Cards range FR to VG-EX.
