As a community service, the U. S. Postal Service® offers collectible postmarks. The Postmark America® program is designed to feature graphics related to a theme or image that pertains to a specific tourist location, town, or region. The postmark is applied upon request to both outgoing mail and on hand-back philatelic collectibles. These postmarks will be available any day a participating Post Office™ is open. All requests must bear at least minimum First-Class Mail® postage. Customers must present their items for post-marking on or before the official postmark date requested at the address listed in this article.
