This First Day Cover features a detailed cachet with a blue ink illustration of a bald eagle in flight, set against a light cloud background. The stamp, a non-denominated 'B' rate with a purple eagle design, is affixed to the top right and tied by a circular machine postmark from San Francisco, CA, dated March 15, 1981. The cover commemorates the 1981 postal rate increase, with text indicating 'SHEET-COIL BOOKLET' and the artist's signature 'Gamm' on the cachet. The envelope is in clean condition with clear, legible details.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
