U.S. Postal Service to Issue New Priority Mail and Priority Mail Express Stamps
Big Bend and Grand Island Ice Caves Featured on Stamps

WASHINGTON — The U.S. Postal Service today revealed two additions to the 2020 Stamp Program: Big Bend and Grand Island Ice Caves. Both stamps will be released on Saturday Jan. 18, 2020. There will be no national first-day-of-issue ceremony for these stamps. Details on obtaining first-day-of-issue cancellations will be announced in a future Postal Bulletin issue.

These stamps are a convenient way for customers to pay for Priority Mail and Priority Mail Express Flat Rate shipping with a single stamp. Priority Mail is a fast domestic service that includes flat rate shipping in one, two or three business days based on where your package starts and where it’s being sent. Priority Mail Express is the fastest domestic service, with limited exceptions; available 365 days a year, with a money-back guarantee and delivery shipping to most U.S. addresses, including PO Boxes.

Grand Island Ice Caves

With this new Priority Mail Express stamp, the Postal Service celebrates the winter beauty of the Grand Island Ice Caves in Lake Superior. Located near Munising on Michigan’s Upper Peninsula, Grand Island is marked by massive sandstone bluffs. Impressive in any season, the bluffs are especially dramatic in winter when lake water seeps into the crevices and caverns, forming magnificent ice curtains and icicles that hang like stalactites from ceilings. The stamp art features a colorful illustration of how one of these ever-changing ice caves might appear from the inside looking out toward the west at sunset. Art director Greg Breeding designed the stamp with original art by Dan Cosgrove.

Customers may purchase stamps and other philatelic products through The Postal Store at, by calling 800-STAMP24 (800-782-6724), by mail through USA Philatelic, or at Post Office locations nationwide.
