To commemorate USA’s 250th anniversary, we invoke Rebellion! as the mail art theme for mail art at Boston 2026 World Expo. The 12th decennial international stamp show in the United States will convene on Boston’s historic seaport. The Rebellion! mail art show will commence May 23-30, 2026 at Boston Convention and Exhibition Center.
To participate, please design a mail piece around the Rebellion! theme. We will display the front and back side of the mail piece (do not send contents). You may place a cardboard stiffener inside an envelope. Please send only flats: envelopes and postcards. Maximum size is A4 (21cm x 29.7cm), or slightly over letter-size (9 x 12 in.)
Deadline: Submit by May 1, 2026.
Send your mail art to:

We will strive to document the work as accurately as possible.
The proceedings will be available at https://rebellion2026.blogspot.com/ . Each mail piece will be uploaded shortly after it is received. The work will NOT be returned.
If you do NOT want your return address publicly displayed at the venue or documented on the internet, place your return address on the back of the mail piece. The back and your address will not be displayed.
