The Artmaster cachet features green-toned illustrations of classical architectural column capitals and details, including an ornate Corinthian capital, a decorative basket-weave column, and classical pilaster details. The text 'HONORING AMERICAN ARCHITECTURE' and 'First Day of Issue' appear in green ink alongside the artwork. The 15-cent stamp depicts Lyndhurst mansion in Tarrytown, NY, designed by architect A.J. Davis (1803-1892), rendered in black engraving on a buff background with red 'Architecture USA 15c' text. The circular machine postmark reads 'NEW YORK, NY / OCT 9 / 1980 / 10001' with a machine-printed 'FIRST DAY OF ISSUE' slug cancellation.
Mistral
This First Day Cover features a 15-cent stamp depicting Lyndhurst, a Gothic Revival mansion in Tarrytown, NY, designed by architect A.J. Davis. The cachet artwork by Artmaster showcases classical architectural elements in green tones, including a Corinthian capital, decorative pilasters, and a woven basket design. The stamp is canceled with a circular postmark from New York, NY, dated October 9, 1980. Additional text includes 'HONORING AMERICAN ARCHITECTURE' and 'FIRST DAY OF ISSUE'.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
