These 'Speak Doctor' posters and prints are great for decorating your room or office. To use them, simply choose a nice spot on the wall, and use tape or nails to hang them up. Make sure the surface is clean and dry before hanging. As for maintenance, avoid exposing them to direct sunlight for long periods as it may fade the colors. Also, keep them away from moisture to prevent damage. If there's a little dust on them, you can gently wipe them with a dry cloth.
