Did you check any other sites? Or browse for images of Foote during his time with the Cubs? I did one google search and found his 1982 Topps card picturing him wearing a similar jersey with #8 on the front.

This is a realy great style of jersey. If I was a little more flush with cash I'd buy it in a heartbeat.
