tbobDan means if you could post a scan (computer picture) of the front and back of the card here so it can be seen, the answer could be forthcoming. I am not aware of any reprints or reproductions which have blank backs however a backing could have been peeled or skinned off. A scan would show the presence of proof marks on the cards which all T206 proofs have. If it doesn't have it, it could be cut from an advertising poster although again I have never heard of a Wagner on any advertising poster.
