The cachet on the left side of this air mail envelope features teal/green ink artwork depicting an aerial view of Zanesville, Ohio, with its famous Y-bridge visible over a river, surrounded by the city landscape. The text 'U.S. AIR MAIL FIRST FLIGHT' appears at the top of the cachet with 'Zanesville OHIO' prominently displayed below the vignette. The stamp is a red U.S. 5-cent Air Mail stamp (Scott C32 or similar) cancelled with a machine cancel from Zanesville, Ohio dated November 1, 1947 at 10 AM. The reverse shows a transit backstamp from Columbus, Ohio AMF (Air Mail Facility) dated November 1, 1947 at 12:30 PM, along with an RMS (Railway Mail Service) oval marking.

(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
