This rare set of 12 cards surfaced in 2006. It contains a dozen images of Jack Dempsey in training packaged in a cardboard clamshell box and was sold at Dempsey’s training facility in Montana as a souvenir. These cards are nearly impossible to find. One complete set is known in the Hobby; present whereabouts not known. The SGC population is 8 cards; PSA has never graded one. We are pleased to offer one of the eight cards an SGC 50 graded example of Champion Jack Dempsey and Burke. It is the sole graded example of this card and depicts the champion sparring with English heavyweight Martin Burke.
