Dominated by a patriotic motif, this rare postcard includes a portrait of Johnson above an illustrated image of a scene from his recent bout with Jeffries. The caption at bottom reads, "Jack Johnson, Champion of Champions, Defeating James J. Jeffries, July 4th 1910. Reno, Nevada." EX-EX+, with only a minor corner crease (visible only on back) and the lightest of toning.
