Although he lived to 1977, this is an extremely difficult card to find signed. I have only ever seen four of them come up for auction, and never once individually.
Signed 1921 Exhibits are tough enough to find signed as is, let alone HOFers from the set, let alone HOF rookies from the set.
Back is clean save for what was likely the original price of the card, which is written in pencil in a top corner.
Asking SOLD delivered.
