The stamp–actual U.S. postage–will be made available for sale on the UNH Cooperative Extension website, in Extension offices in every county, and in some retail outlets.
Help us commemorate our 100th anniversary. Design our stamp! The contest winner will be recognized in the media, at our centennial exhibits, and in centennial-related promotions.
