The Kittery, ME and Portsmouth, NH Post Offices will be offering special pictorial postmarks to commemorate the 50th anniversary of the loss at sea of the US Navy nuclear-powered submarine USS Thresher.

On Wednesday, April 10, Kittery Postmaster John Wickman and Portsmouth Postmaster Richard Provencher and their staffs will be available at their respective post offices to stamp letters and postcards with a unique postmark documenting the occasion. Specially authorized by the U.S. Postal Service, this special postmark is a way to take home an inexpensive souvenir of the occasion.

Customers can also request the special postmark free-of-charge by mail for 30 days after the event by sending a self-addressed, stamped envelope containing the letter or envelope they wish to be cancelled to: Postmaster, 80 Daniel Street, Portsmouth, NH 03801-9998, or Postmaster, 10 Shapleigh Road, Kittery, ME 03904. 

“We will be happy to cancel and return by mail any letters that our customers mail to us,” said Wickman. “Customers may bring in their own envelopes to obtain a postmark that they can take home as a keepsake,” added Provencher.
