Aaron Help, Please
 

A trusted collector offered me the following Hank Aaron signed cards that were signed through the mail in the 1970s. I have a number of Aaron autographs that I obtained in person during an overlapping time period (early 1970s) and there are similar characteristics, but not an obvious match. Mine were signed in person at hotel lobbies where they were likely more rushed than the case where he would be sitting down answering fan mail.

I would be grateful for any opinions regarding authenticity of these autographs.

Many thanks in advance.
