From the USPS on October 29, 2025:

This booklet of 20 stamps features three of winter’s most spirited small mammals: two eastern chipmunks, an eastern gray squirrel, and an American red squirrel. The designs capture the resourcefulness and adaptability that help these animals thrive when temperatures drop. From busy foragers to cozy hibernators, they remind us that winter can be full of charm. “When you see the booklet as a whole, the animals’ faces popping up from the snow has a playful effect,” explains Derry Noyes, an art director for USPS who designed the issuance. “The stamps are fun and uplifting. I hope they make people smile, especially in the heart of winter.”

More details will be posted below the line, with the most recent information at the top.
