Hank Aaron autograph help
 

The attached scan shows three 1974 Topps autographed Aaron cards. They were a part of a large estate with other signed cards that appear to be authentic. I need some help/opinions about the authenticity of these Aaron autographs. Any help would be greatly appreciated.

Thanks.

PS, the scan that I attempted to attach is one page pdf (676 kb), but exceeds the limits of 19 kb. Any suggestions? I could also email the scans to anyone willing to provide an opinion. Please let me know. Many thanks.
