Photograph of cachet art for Contract Airmail Route 1002
This image shows the artwork All American Airways (AAA) used to represent the experimental airmail route designated "1002." The route ran between Pittsburgh, Pennsylvania, and Clarksburg, West Virginia. The image was reproduced on envelopes carried on the service's first flight.
This experimental service allowed airmail to be exchanged between an airplane and a postmaster without landing. Postmasters placed the outgoing mail in large rubber containers that were attached by rope to a pair of goal posts. The airplane would swoop down and use a hook attached to the belly of the craft to snatch the mailbag. Mail for the town was placed in another container and dropped from the airplane onto the field.
