Postcrossing announced that the US Postal Service will issue new Postcrossing “Global Forever” stamps for international mail, featuring four playful designs in a rare triangular shape. The stamps launch May 26, 2026, with a commemorative ceremony and daily Postcrossing meetups at the Boston 2026 World Expo, and they will also be available online and at post offices nationwide. The designs were created by Antonio Alcalá and illustrated by Jackson Gibbs.
