This is the new love skywriting pane of 20this new issuance is a cheerful and romantic continuation of the US postal service tradition of creating stamps that celebrate love. Skywriting had its heyday as an advertising medium from the 1920s to the 1950s, promoting everything from soft drinks to bikinis. Messages are created by a small airplane that emits vaporized fluid from its exhaust system to form letters in the air. Still used occasionally for advertising slogans, skywriting more commonly broadcasts romantic—and very public—declarations of love. The love skywriting stamp is being issued as a forever stamp. This forever stamp will always be equal to the current first-class mail one-ounce price. Issue date: February 14, 2017, made in the USA.
