Leslie Hindman Auctioneers ran The Official 14th Annual National Sports Collectors Convention Auction on July 22 and 24, 1993. This 1948 Leaf boxing complete set on an uncut sheet was one of its standout items.
The sheet was lot 482 and was described as follows, “1948 Leaf Boxing Complete Set Uncut Sheet, 49 cards make up this rare sheet. Joe Louis, Jake LaMotta, Tunney, Conn, Corbett, Jack Johnson, Sugar Ray Robinson, Max Baer, Jack Dempsey, etc. Sheet is in excellent to mint condition. $5,000/7,000.”
I’m unsure what it sold for in 1993, but REA re-sold the 17 x 20-inch sheet in the fall of 2020 for $3,120, describing it as having a Vg appearance despite numerous imperfections.
