In 1978, the same year that Ben & Jerry’s Ice Cream was founded in Vermont, two entrepreneurs in New Hampshire started a small poster company that evolved into White Mountain Puzzles. White Mountain Puzzles has grown into one of the top puzzle brands in the United States! White Mountain Puzzles is still located in Jackson, NH (pop. 850), in the White Mountain National Forest, just a few minutes from Mount Washington (elevation 6288 feet), in a beautiful village dotted with turn-of-the-century inns and B&Bs. Every White Mountain Puzzle is manufactured in America. Every year our quality improves. All our puzzles are interlocking and made of sturdy blue chipboard on recycled paper. Our 1000 piece puzzles are the LARGEST IN THE INDUSTRY, measuring 24" x 30" when finished.
