The Artmaster cachet features a blue and red engraved illustration of a classical female figure (Columbia or Lady Liberty) holding a shield with an American flag design, rendered in patriotic red and blue. The stamp is a variable-rate PMC (Postage and Mailing Center) coil stamp printed vertically, showing a USA eagle/shield design in red on a tan/orange background with the denomination printed by machine. The postmark is a standard machine cancel from Oklahoma City, OK dated August 20, 1992, with ZIP 73125, accompanied by a 'FIRST DAY OF ISSUE' machine slogan cancel. The back of the cover provides detailed explanatory text about the PMC stamp program and identifies the cachet producer as Artmaster, Inc., P.O. Box 7156, Louisville, KY 40257-0156.
Mistral
The cachet artwork features a classical female figure, likely representing Columbia or Lady Liberty, holding an American flag shield. The design is rendered in blue and red engraving, with the text 'VARIABLE RATE ISSUE' and 'First Day of Issue' printed in red. The stamp is a vertically printed coil stamp with an eagle and shield design, cancelled with a circular postmark reading 'OKLAHOMA CITY OK AUG 20 1992.' The cover is in excellent condition with clear, legible printing and no visible damage.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
