This Wolfenstein The New Colossus metal sign is a great collectible. You can hang it on your wall to show your love for the game. To hang it, just use a regular nail or a wall hook. Make sure to choose a strong hook as the sign has some weight. When cleaning, use a dry or slightly damp cloth. Avoid using harsh chemicals as they may damage the metal finish. Keep it away from direct sunlight for long periods to prevent color fading. If you plan to move it, hold it firmly by the edges to avoid bending or denting.
