To use your Rad Dalek poster, simply find a spot on your wall that you'd like to decorate. You can use nails or wall hooks to hang it up. Make sure the surface is clean and dry before hanging. As for care, avoid exposing the poster to direct sunlight for long periods as it may fade the colors. If it gets dirty, you can gently wipe it with a soft, dry cloth. Keep it away from moisture to prevent damage. That's it, and enjoy your unique wall decor!
