“A to Z: P” is the theme for today’s Sunday Stamps.

P is for Postcrossing

And this, from the Postcrossing blog…..”The United States Postal Service is issuing some shiny new Postcrossing stamps on May 26, 2026. The new Postcrossing stamps are triangular, which is a pretty rare format for USPS. That means you can place one right on the corner of a postcard for an especially cool look. There are four different stamps to choose from. They are global forever stamps, which means they are the international postcard (or letter) rate, and you need one single stamp to send a postcard abroad. 

Visually, they’re a lot of fun: bold colors and playful scenes with lots of tiny details. They were designed by Antonio Alcalá and illustrated by Jackson Gibbs, and the result is energetic, bright, and unmistakably Postcrossing.”
