This is a wonderful gift or "must-have" for any boat lover. It measures 4 1/2 x 4 1/2 inches and is 1/2 inch thick. Each piece comes from the hull of the Battleship and will vary slightly. The steel has not been altered in any way and has been cut with a water jet. Great for display on a bookcase, mantle or desk. Each piece comes with a signed Certificate of Authenticity.
