The similarity between postage and revenue stamps caused some to think nothing of using them interchangably.

This tintype carte bears a revenue stamp on its mount canceled by "O.J. Hamlin, Artist". Another revenue on the back of the tintype itself is tied by a dateless postal circular marking that reads "CHASE MILLS N.Y."

This revenue stamp seems to have been accepted to pay the 2¢ drop rate. While such uses are known for letters, this item is the only use of revenues for both postage and taxation on a single item that I have encountered.

The facts that the postal marking ties the stamp and that I.R.S records show that Hamlin operated a studio a plausible 25 miles from Chase Mills seem to authenticate the item.

What is puzzling however, is how it was addressed. Perhaps a lost enclosure was slipped into the tintype holder. Or is it possible that the photographer's cancellation was the address? The portrait is of a woman. A sitter/admirer perhaps?...
