Description
Issued in 1970, United States Scott #1413a is a four-stamp se-tenant block from the Environmental Protection commemorative series, released during a pivotal moment in American environmental awareness. Issued the same year as the first Earth Day and the founding of the Environmental Protection Agency, this set reflects growing public concern over pollution, conservation, and sustainable stewardship of natural resources.
Each 6-cent stamp in the block pairs an image of the Earth with a specific environmental message: Save Our Cities, Save Our Soil, Save Our Air, and Save Our Water. The designs combine modern graphic elements with strong, direct slogans, emphasizing human responsibility for the planet’s future. Subjects include urban development, farmland, wildlife, and aquatic life, reinforcing the interconnected nature of environmental issues.
Printed in multicolor lithography, the stamps exhibit bold color contrasts and a distinctly modern aesthetic typical of late 1960s and early 1970s U.S. commemoratives. The se-tenant format was intentional, encouraging the stamps to be collected and displayed as a unified message rather than separated.
This example is offered mint never hinged (MNH), with full original gum and no hinge marks, disturbances, or thinning. Color is bright and fresh throughout, impressions are clean, and perforations are intact. MNH se-tenant blocks from this era remain popular with collectors of thematic material, environmental history, and modern U.S. stamps.
