The cachet features a yellow map of Alaska with the Trans-Alaska Pipeline route marked in red, running from Prudhoe Bay to Valdez, against an orange/red background on the right side. The cachet text discusses the discovery of North America's largest oil field at Prudhoe Bay and Alaska's vast energy potential including coal, natural gas, uranium, geothermal, and hydroelectric resources. The stamp is the 13-cent USA 'Energy Development' issue depicting a stylized sun with a human face, an orange landscape, and industrial elements. The postmark is a standard circular machine cancel from Washington, DC 20013, dated October 20, 1977.

This First Day Cover features a bold yellow and red cachet with a map of Alaska highlighting the Trans-Alaska Pipeline route from Prudhoe Bay to Valdez. The stamp, located in the upper right, depicts a stylized sun with a human face and the text 'ENERGY DEVELOPMENT,' symbolizing renewable energy. The circular postmark reads 'WASHINGTON, DC OCT 20 1977' and cancels the stamp. Additional text on the envelope describes the energy potential of Alaska and the challenges of developing its resources. The cover is in excellent condition with clear, legible printing and cancellation.
(The automatic summaries sometimes misidentify the postmark as part of the cachet artwork.)
