The card in question on ebay is......
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&rd=1&item=220142267373
The card posted by Brian W (on the link I have provided above) is identical, but in a Beckett holder.
Click on both links and do an A-B comparison.
If I undertood Art M's story correctly this is the DRUM back from the original Donovan card that it was on.
The Cobb in your scan appears to be a 2nd Cobb/Drum and is a different one than the one currently on ebay.
Perhaps, Art will chime in and resolve this enigma.
