To use this puzzle, simply spread out all the pieces on a flat surface. Start by sorting them by color and edge pieces. Then, gradually fit the pieces together to form the image of The Goonies movie poster. You can work on it at your own pace, either alone or with others. When you're done, you can display it as a cool decoration. As for maintenance, keep it away from moisture and direct sunlight to prevent fading. If it gets dirty, you can gently wipe it with a soft, dry cloth. Just be careful not to bend or damage the pieces.
