 Hi Peter,
   The only Shad Barry with a Drum back that I've seen was part of the group that sold in Hunt auctions not long ago.
 I have a dozen Drum's and this card doesn't look right for many reasons...
   For one, the ink is the wrong color. I agree with the skinned back/stamp theory, as the ink from the stamp appears to have pooled and soaked into the untreated paper.
   Be well Brian
