Mistral
The cachet features black silhouette artwork of a golfer and caddie walking together, with the golfer holding a golf club and the caddie carrying a golf bag. The text 'Houston Open '94' is printed in bold black letters at the bottom. The Shell Oil company logo is printed in black at the top left and within the text. The cover bears a 29-cent USA stamp with a blue and red eagle design (Scott #2541). The postmark is a circular red cancellation with 'THE WOODLANDS, TX,' a May 1, 1994 date, and a partial ZIP code. The condition of the cover is good, though the postmark is slightly smudged.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
