Jeff, that is my favorite pre-war card and your copy is an absolute beauty! Sold my copy toward this below, which is my favorite graded card. Hoping to replace my Cobb at the National this year.
There are just 19 signed 1952 Topps Mantles in the PSA pop report. Of those, only this one was signed in his playing days, March 29, 1968 to be precise, and the kicker is the very man who had it signed was the one who pulled it from a pack as a boy!
