"AMERI-CANS" puzzle. Over 3,000 aluminum cans were used to create this image… or the same amount discarded in just the United States every second. When finished, hang this puzzle on your wall or plant the pieces in the soil to grow wildflowers. This puzzle has been backed with paper that is recycled, renewable and also imbued with the seeeds of many wildflower species. Soak the pieces overnight in water and plant them in the soil or pot. Water them daily until they bloom to reduce your carbon footprint. 500 piece jigsaw puzzle.
