And for those who don't know, Halper had the largest memoribilia collection anywhere, after the Hall Of Fame. We had a family friend who was friends with Halper. Supposedly, he had one of those mechanical moving racks in his basement that they have at the dry cleaners for all the jerseys and uniforms he had accumulated. After Halper passed away, I think it was noted that he had a jersey or uniform from nearly ever HOFer.
Halper amassed some 80,000 items, including uniforms of many Hall of Famers, an original ticket from the first World Series in 1903 and the jersey Lou Gehrig wore in his farewell speech at Yankee Stadium in 1939. Halper also owned oddities such as the false teeth worn by Ty Cobb, baseball's all-time leading hitter.
Also in Halper's collection were uniforms worn by Cobb, Walter Johnson, Cy Young and Mantle, during his rookie season of 1951. Halper also had the contract finalizing the sale of Babe Ruth from the Boston Red Sox to the Yankees, and a Honus Wagner baseball card.
