Offering an old wax sealer marked “Ry Ex. Agy.  INC,  Rome, NY” used in the station after 1929.
According to the official guide, this town was served by the New York Central RR and the New York Ontario & Western Ry, but not sure which depot this came from  (did they use the same building?).
These were used by the station agent in the depot when he conducted express business.   He would put a wax seal on envelopes and parcels to ensure their security in transit to their destination.
“In July 1918,  the four major and three minor express companies were consolidated as American Railway Express, Inc.   In March 1929, the assets and operations of American Railway Express Inc. were transferred to Railway Express Agency.”
Very good condition.
