This First Day Cover celebrates the Costa's Hummingbird 29-cent booklet stamp (Scott #2643) from the 1992 Hummingbird series, designed by Chuck Ripper. The Technical Cachets cachet features a minimalist black line-drawn hummingbird in flight with motion lines, accompanied by extensive philatelic reference information; the stamp itself displays the bird perched near vibrant red tubular flowers in rich photogravure colors. Postmarked June 15, 1992, in Washington, DC, this is cover #3 of the 10-cover series.
