To use these posters and prints, simply choose a spot on your wall and hang them up using appropriate wall - hanging tools. You can put them in your living room, bedroom, or even your office. As for maintenance, keep them away from direct sunlight to prevent fading. Wipe them gently with a soft, dry cloth if they get dusty. Be careful not to use any harsh chemicals or abrasive materials on them, as this could damage the print.
