I truthfully do not know if they are reproductions. I found them in my grandmothers stuff when she passed. I will take and post the back side if I can. Thanks for asking.
I am so sorry can not add other pics now since so close to bidding being over. Will try to explain the back. There is a small box that says "STAMP" in fancy print, it also says "POST CARD", the "C" in card is fancy letter and scroll work under "POST CARD", a divided line on card, one side says " FOR CORRESPONDENCE" and other side says "FOR ADDRESS ONLY". Hope this helps. Thank you.
