On this stamp, a West Indian manatee gently lolls underwater, just beneath ripples on the surface. Many types of hungry freshwater fish clean algae off a manatee’s skin, and the West Indian manatee on the stamp is accompanied by two such fish.

Illustrated by Nancy Stahl, the vertical stamp’s art is predominantly aqua-colored, with the manatee’s body rendered in shades falling between pale green and gray. At the top left of the stamp, the words “forever usa” appear in lowercase sans serif italics. “MANATEE” is printed in rounded capital block letters in pale aqua.

The booklet cover features an enlarged crop of the stamp artwork, with the words “SAVE MANATEES” in white capitals.

Derry Noyes, an art director for the Postal Service, designed the stamp and booklet using Stahl’s digital illustration.
