To use these posters and prints, you can simply hang them on your wall using a thumbtack or a picture - hanging kit. Make sure to choose a well - lit area so that the message is clearly visible. When it comes to maintenance, keep them away from direct sunlight and moisture to prevent fading and damage. If they get dirty, you can gently wipe them with a dry cloth. And remember, don't bend or fold them to keep their good condition.
