Jusqu-a Airmail Markings- A Study Ian Mcqueen 🎯 Ad-Free

An airmail etiquette (blue "Par Avion" label) needed to be "canceled out" or qualified because the flight was unavailable for the remainder of the route.

McQueen’s central thesis is compelling: the Jusqu’à marking is not merely a technical annotation but a “diplomatic gesture in ink.” It emerged from a fundamental logistical problem in the 1920s and 1930s: how to integrate new, faster air routes with existing, slower surface mail networks. When a letter traveled from, say, London to Sydney, it might go by train to Marseille, then by air to Cairo, then by ship to Bombay, then by air again to Singapore. The Jusqu’à marking indicated the specific point up to which air conveyance was paid for or authorized. Beyond that point, the mail reverted to surface transport unless further paid. McQueen masterfully demonstrates that these markings are therefore a cartography of limitations—showing exactly where the sky ended and the sea began. Jusqu-a Airmail Markings- A Study Ian McQueen
