From the USPS press release November 15, 2024:

Useful for mailing a 1-ounce letter to any country in which First-Class Mail International service is available, this stamp carries with it a bit of history. The colorful compass rose was drawn in a school geography notebook by Lucia Wadsworth, the aunt of poet Henry Wadsworth Longfellow, when she was 10 years old. Greg Breeding, an art director for USPS, designed the stamp.
