Dave-
I have this Wagner I'd consider parting with... It's from Wagner's estate and has a full PSA letter, too. The signature is on the back of an envelope. What's more interesting is the fact that the envelope is addressed to Fern Bell, who played for the Pirates in '39 and '40. Wagner signature remains unaffected by the watermarks on the front. Also a very bold signature in person. Shoot me an email if you're interested.
