Plug Bayonet

Plug Bayonet by an unknown artist. The image shows a black and white photograph of a dagger or short sword. The object has a dark metal handle with a decorative knob at the end. A metal guard with two quillons is in the middle of the object. The blade appears to be made of a lighter, corroded metal. The blade has an uneven edge and a pointed tip. The blade's surface shows signs of heavy corrosion or wear. A ruler is in the bottom-left corner for scale. A small plaque in the bottom-right corner reads "THE METROPOLITAN MUSEUM OF ART 1928". The background is a plain light surface.
