It looks like it may well be his, but is post-playing career. Aaron, Eddie Mathews and Warren Spahn 1980s Braves pullovers periodically surface that are attributed either to extra coach status or Old-Timers games. The photos look promising, although I'd have to see it in hand to make a final determination.

Also, the collar Wilson tag is partially obscured. What size is it? It looks like 46, but I'm not sure.
