Bare-knuckle boxer Jake Kilrain lost to John L. Sullivan in the last bare knuckle boxing championship in 1889. Kilrain's trainer threw in the towel after 75 rounds (!) the $5000 purse awarded to Sullivan. In later years the two would become close friends Kilrain serving as a pallbearer at Sullivan's 1918 funeral. The finest example graded by SGC with no examples higher Kilrain is pictured here two years prior to the famed fight. A truly exceptional card.
