Looking for opinions on the 1971 Topps Jackson Autograph below. His signatures seems to vary quite a bit. This one looks the closest...

Then again, I don't have a good average at this! I appreciate your time in advance!

Thanks

Looks like rare genuine "Peggy Jackson" auto.

Im going with no. While with any card that old, its possible its a vintage signature. But I dont believe that is Reggie’s vintage signature either.

Here’s my 1971 topps signed.
