FS: 1921 W521 George Sisler - One of Just 6!

[robw1959]

Very rare issue, as only 6 of these have been graded by SGC and PSA combined, and its likely that all are reverse-negative printings like this one. No creasing; just an off-center cut, probably by a child in the 1920s. Obviously few sold examples exist, so I don't quite know how to price it. Asking $200 delivered, or best offer, PayPal preferred.
