This official First Day Cover marks the introduction of the "D" rate domestic postage stamp (Scott #O138, part of the Official Mail series for penalty mail use), a green definitive featuring a bald eagle in flight clutching a bundle of letters, symbolizing swift and secure government communication. The stamp's design includes the eagle with outstretched wings over a postal sack overflowing with mail, emphasizing the eagle as a national emblem tied to U.S. postal service. The cachet artwork presents a powerful, dramatic scene: a majestic bald eagle soaring upward with wings spread wide, carrying a large mail sack overflowing with letters and documents in its talons, set against a textured background for depth and motion. Postmarked February 1, 1985 (issue date), in Los Angeles, California—with a clean "First Day of Issue" cancellation (ZIP 90052)—this cover appeals to Official Mail specialists, bald eagle and wildlife philatelists, postal rate change collectors, or those interested in governmental and patriotic themes. It is in pristine unaddressed vintage condition with rich green tones, sharp detail, and no faults, perfect for specialized or avian collections.
