This ArtCraft cacheted First Day Cover bears a block of four 13¢ Energy Conservation / Energy Development stamps, officially postmarked Washington, DC on the first day of issue.
Issued during the height of the 1970s energy crisis, the stamps highlight the dual national priorities of conserving existing resources while developing new ones, reflecting the era's push for both efficiency and expanded domestic production.
The striking vertical design pairs a radiant sun-face with an oil-derrick motif, emphasizing the link between solar energy and conventional fuels; the ArtCraft cachet illustrates offshore drilling alongside atomic and hydroelectric symbols.
A fine addition to any energy, environment, or 1970s topical collection, the cover remains in clean, collectible condition with sharp strikes and vivid color.
