Stamp Announcement 21-27: Happy Birthday Stamp

This stamp will go on sale nationwide September 9, 2021, and must not be sold or canceled before the first-day-of-issue.

This Happy Birthday stamp conveys exuberant greetings by calling to mind the childhood excitement of a birthday party.

Featuring a digital illustration by Rodolfo Castro, this stamp was designed by Lisa Catalone Castro and Rodolfo Castro. Ethel Kessler served as art director.
