To use these posters and prints, simply find a wall in your room where you want to display them. Clean the wall surface first to ensure better adhesion if you're using adhesive. If you're using frames, choose a frame that matches the style of the print. When it comes to maintenance, keep them away from direct sunlight to prevent fading. Wipe them gently with a dry cloth if they get dusty. Avoid using any harsh chemicals on them. Also, be careful not to bend or crease the posters and prints, as this can damage the image.
