The cachet features a black ink illustration of a Formula 1 open-wheel race car in action, depicted with motion blur effects suggesting speed, set against a stylized racing environment with pit lane structures visible. The cancel/cachet text reads 'Detroit Grand Prix' in script lettering with the date June 7, 1992. The stamp is the USA 29-cent Flag stamp (two American flags waving), and the pictorial station cancel reads 'Belle Isle Park Station, Detroit, MI 48207.' The cover is unaddressed and in excellent condition.

This First Day Cover features a black ink cachet with dynamic artwork of a Formula 1 open-wheel race car in motion, with blur effects suggesting speed, set against pit lane structures. The stamp is a 29-cent U.S. flag definitive (Scott #2522). The postmark is a pictorial cancellation with text and possibly faint imagery, dated June 7, 1992, from Belle Isle Park Station in Detroit, Michigan. The cover is in clean, unused condition.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
