Signed grocery receipt from Babe Ruth on Easter 1930. I purchased this from the family of the person who delivered groceries to the Ruth's. The family was aware that their family member met Babe Ruth but did not know that he had kept a signed receipt until after his wife's death. LOAs from the family, Bill Diebold of Everything Baseball and PSA/DNA (LOA number I88910).
My greatest eBay score. I recognized The Big Train's autograph as soon as I saw it. The seller had a BIN of $75 and I happened upon it less than an hour after it was listed.
