These two cards are one of those items one can  come across very occasionally. Especially since they have not been reported in publications. These are two cards that fulfilled the function of accrediting in the franking machine the necessary fund to make effective the collection to the company that used this service.
They are a pair of cards in medium cardboard, one of them has on the back the impression of the franking agent.
Rare unique and exceptional article.
How much do you consider the value of an article of which there is no known report, how many pieces will there be?
