1991 50-cent Harriet Quimby Pioneer Pilot US Airmail Postage Stamp

This item is a 50-cent US Airmail postage stamp issued in 1991, featuring Harriet Quimby, the first American woman to become a licensed pilot. The stamp is printed on white paper stock with a colorful illustration that depicts Quimby in her signature purple flight hood and goggles, with a vintage Bleriot monoplane visible in the blue-sky background. The text on the right side of the stamp reads 'Harriet Quimby Pioneer Pilot,' 'US Airmail,' and the denomination '50.' It is an adhesive postage stamp with perforated edges. This specific example appears to have been crudely removed or cut from an envelope or sheet, as it retains a wider white paper border around the actual perforated area. The condition displays visible wear: the top right corner of the backing paper is bent and slightly torn, there is some minor grime or foxing on the white margins, and the perforations appear slightly softened. While it shows no clear cancellation mark on the face, the rough edges suggest it is likely a used or 'hinged' specimen. The printing quality is standard for late 20th-century government-issued postal stamps, utilizing a multi-color lithographic process.
