Thoughts on the Early Sandberg Auto?
 

I'm fairly certain this is good, but given the surprisingly limited amount of examples from the time-period to verify, wanted to run this by the group (the verbiage makes these sound like an "Appearance Photograph" aka only supplied at events these players were at (also have a Bowa from the same "release"))

Thank you! I think it’s close enough in the R, Y, and S to justify putting in the “to the Authenticator” stack

I don't have a scan of it but I have a 1985 Donruss Diamond King I obtained at a card show appearance that matches up very nicely with the OP's example.

It’s good. Have many Sandberg early autos and this one looks just like those.
