USPS Grand Island Ice Cave Express Priority Stamps

On January 18, 2020, in Munising, MI, the United States Postal Service^® will issue the $26.35 Grand Island Ice Caves Priority Mail Express^® stamp in one design, in a pressure-sensitive adhesive (PSA) pane of four stamps (Item 129100). The stamp will go on sale nationwide January 18, 2020, and must not be sold or canceled before the first-day-of-issue.

With this new Priority Mail Express stamp, the United States 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, they 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.
