This MasterPieces 24" x 18" 550PC Brilliance Puzzle captures the brilliance of life. "Tidal Treasures" features a colorful assortment of seashells. The shores of Glacier Bay, Alaska see a diverse buffet of high-quality food items, such as mussels, clams, chitons, and barnacles. Crows and ravens will pick up clams and mussels, fly up to 15 feet and drop them, devouring the contents when the shell eventually cracks open. The native people, the Hoonah Tlingit, have a saying: "When the tide is out, the table is set." To reduce its impact on our environment, the chipboard used in this puzzle is made of recycled material.
