Wilson ( Borstelmann & Cia, Pernambuco, Brazil) via Graf Zeppelin LZ 127 airmail across the Atlantic. The envelope also features an outline of the Zeppelin with two other Graf Zeppelin stamps on the obverse. It is numbered “16835” on the obverse and “4674” on the reverse.

Footnote: The Graf Zeppelin was a German passenger-carrying airship that was operated commercially from 1928 to 1937. When it entered service in late 1928, it was the first commercial passenger transatlantic flight service in the world. Passengers paid premium fares to fly on-board of the Zeppelin, while others who could not afford the airfare sent airmail.
