In the article titled “Stamp Announcement 19-27: Woodstock Stamp, in Postal Bulletin 22523, (7-4-19, pages 37–38), the first-day-of-issue was listed as August 2019. More specifically, the Woodstock stamp will go on sale nationwide August 8, 2019, and must not be sold or canceled before the first-day-of-issue.
In the “How to Order the First-Day-of-Issue Postmark” section, the deadline for submitting First-Day Covers was left unannounced until a later date. The First-Day Covers submission deadline is December 8, 2019.
Additionally, the Special Dedication Postmarks are now available and shown here.
Only the pictorial postmark shown here is permitted for the Woodstock 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 approved special pictorial image is prohibited.
To finalize the Woodstock 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.
