The cachet features a blue-toned photographic image of the Skylab space station orbiting above Earth with clouds visible below, with 'SKYLAB' printed in large dark red letters at the top. The lower portion contains a detailed data table in blue and white listing crew information, mission dates, durations, and revolutions for OWS, SL-1, SL-2, and SL-3 missions. The stamp is the US 10-cent Skylab commemorative (Scott #1529) depicting the station in orbit against a purple/gold background. The postmark is a circular hand cancel from Houston, TX dated May 14, 1974, with ZIP 77013, and 'FIRST DAY OF ISSUE' printed to the right of the stamp.
Mistral
This First Day Cover commemorates the Skylab space station with a vivid blue-toned cachet featuring a photographic image of Skylab orbiting Earth, with 'SKYLAB' in bold red letters. The stamp depicts an astronaut performing maintenance on Skylab in space, with 'Skylab' and 'US 10c' inscribed. The postmark is a circular cancellation with 'HOUSTON, TX' and the date 'MAY 14, 1974'. Below the cachet artwork, a detailed data table lists crew names, mission dates, and flight data for the four Skylab missions (OWS, SL 1, SL 2, SL 3). The cover is in excellent condition with clear, legible text and imagery.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
