This official ArtCraft first day cover features the 1974 10¢ Preserve the Environment commemorative stamp issued for EXPO '74, the environmentally themed world's fair held in Spokane, Washington. The cover bears the April 18, 1974 Spokane, WA first-day postmark and includes a colorful cachet depicting leaping salmon, migrating geese, and a stylized map highlighting the fair's conservation message.
EXPO '74 was the first world's fair dedicated entirely to environmental issues, transforming Spokane's riverfront and drawing international attention to pollution control and ecological preservation during a pivotal era of the modern environmental movement.
The cachet artwork cleverly incorporates the fair's iconic structures alongside wildlife imagery, reinforcing the stamp's call to action. The cover is addressed to Dr. Charles R. Martin in Jacksonville, North Carolina, a common practice among mid-20th-century collectors.
A strong addition for topical collectors focusing on environment, world's fairs, or 1970s U.S. commemoratives, with clean cachet and legible postmark.
