In the article “Stamp Announcement 26-27: Declaration of Independence Stamp,” in Postal Bulletin 22703 (5-28-26, pages 45\u221246), there was no mention of a Special Cancellation. This has since been added.
Only the following pictorial postmark is permitted for the Declaration of Independence stamp. The word “Station” or the abbreviation “STA” is required somewhere in the design because it will be a temporary station. Use of any image other than the following special pictorial image is prohibited.
To finalize the Declaration of Independence stamp pictorial postmark art, insert the date, city, state, and ZIP Code™ of the physical location of your event adjacent to the stamp image. Overall dimensions of the pictorial postmark must not exceed 4 inches (horizontally) by 2 inches (vertically). Collectors prefer the dimensions 3-1/2 inches by 1 inch.
The Postal Service™ must make all special postmarks known to collectors through advance publicity in the Postal Bulletin. Therefore, all special dedication cancellations must be reported to Stamp Services 4 weeks before the event using PS Form 413, Pictorial Postmark Announcement/Report. To get a copy of the form, go to blue.usps.gov/formmgmt/forms/ps413.pdf.
