Done
after mailing? So this would be some type of a received stamp? What would the point be of having perfins applied after a mailing went through the post office?
Having looked at the face of the stamp a bit closer, I also wonder where the killer portion of the duplex cancel may have been from (maybe a clue)? It seems to read "C.A."
