The 250 Years of Delivering commemorative pane of 20 stamps must not be split and the stamps must not be sold individually.

Issued to celebrate a major U.S. Postal Service anniversary, 250 Years of Delivering is an illustrated pane of 20 interconnected stamps representing the ubiquitous presence of USPS® throughout the years and the vital role the postal system has played in American life since 1775. The artwork, created by noted artist Chris Ware, shows a bird’s-eye view of a bustling town. Each individual stamp is a frame of sequential art that tells the story of a mail carrier’s daily journey as she walks her route through four seasons. The artwork contains numerous icons representing the Postal Service. On the pane’s verso, text details these items and challenges the game-player to find them. Art director Antonio Alcalá designed the stamps with Chris Ware.
