I'm guessing the stock card is a UX27 or UX27a One Cent. As you see there is stamped "REVALUED 2 c P. O. DEPT." It is not a blank card, there is a typed meeting notice on the back, but this particular card was not addressed nor mailed.
I have several used 1 cent Jefferson post cards, which when the rate went up sometime in the late 1950's I think, all have a 1 cent postage stamp affixed to the left of Jefferson. I've not before seen where the cared is "revalued" by a rubber stamp.
I'm posting this mainly because it is interesting, but if anyone knows more about this phenomena of "revaluing by rubber stamp" please inform us. I am curious as to if this was legitimate and if it was very common.
