923c EF Brief Nachbarortstarif Frankfurt - Neu Isenburg 13.8.46 !RRR

Very rare long-distance letter at the neighboring local transport tariff! According to this regulation of the Reichspost, it was possible in a few places to send long-distance letters at the local rate. Such a regulation existed, for example, in the case of Frankfurt / Main zu Offenbach and Neu Isenburg. Very few, however, knew this possibility. Accordingly, such documents are extremely rare to find!
