This official Art Craft first day cover features the 1974 10¢ Our Mineral Heritage stamp issued June 13 in Lincoln, Nebraska. The cachet was produced for the American Federation of Mineralogical Societies and depicts four classic American mineral specimens—tourmaline, rhodochrosite, petrified wood, and amethyst—arranged around a stylized globe.
The stamp and cachet celebrate the nation’s rich mineral resources and the scientific and economic importance of mining and mineralogy in the 1970s. The issue coincided with growing public interest in earth sciences and the environment, highlighting specimens that represent both beauty and industrial utility.
A notable detail is the diamond-shaped stamp design that mirrors the cachet artwork, creating a unified visual theme across the cover. The postmark is a clean first-day cancel from Lincoln, the designated city of issue.
Addressed to Dr. Charles R. Martin in Jacksonville, North Carolina, the cover carries an interesting connection to a coastal community near the Marine Corps base at Camp Lejeune.
A well-preserved example for collectors of minerals, earth-science topicals, or Art Craft cachets, it displays fresh color and a crisp strike.
