Purchased these at the APS show last August. I'm an avid revenue collector and they looked interesting for many reasons. They were identified as ADX F1 & F2. The dealer I got them from received them identified that way and he knew nothing more about them.
I did NOT find them listed in my US Specialized. So - what catalog can these be found in?
Does anyone know of a specific website with info about these?
What I have found so far does not seem to address these specific stamps.

re: More Info For These?
They look like telegraph stamps, note the "Frank No." and the signature box below. However I do not have any in my telegraph collection and do not see any listed in Scott.
There was an Adams City Express in New York City that issued locals but do not resemble your stamp.
