This Official First Day Cover bears the 13¢ Chemistry stamp issued April 6, 1976, in New York, NY. The colorful cachet depicts laboratory glassware and a scientific graph beneath the heading “HONORING CHEMISTRY.”
Chemistry played a central role in America’s industrial and medical progress during the nation’s first two centuries. The 1976 issue, released during the Bicentennial year, recognized the discipline’s contributions to manufacturing, agriculture, pharmaceuticals, and everyday life.
The stamp design features classic apparatus—Erlenmeyer and round-bottom flasks, a graduated cylinder, and a distillation setup—set against a dotted background, while the cachet adds a dynamic waveform graphic suggesting chemical analysis and experimentation.
A clean, well-centered example with a crisp first-day postmark, this cover makes an attractive addition for collectors of science topicals, American Bicentennial issues, or U.S. postal history.
