To use your 'Epic Roar' poster, simply find a spot on your wall where you'd like to display it. You can use picture hangers or adhesive strips to hang it up. Make sure the surface is clean and dry before attaching. As for care, avoid placing the poster in direct sunlight for long periods as this can fade the colors. If it gets dirty, gently wipe it with a soft, dry cloth. Don't use any harsh chemicals or abrasive materials on the poster. This way, your poster will stay looking great for a long time.
