The image shows a pair of antique door knockers. They are made of metal and have a dark green patina. The knockers have a circular ring in the center, which is used to open and close the door. On top of the ring, there is a small animal-like design, which appears to be a lion's head. The animal's eyes are large and round, and its mouth is slightly open, as if it is snarling. The design is intricate and detailed, with swirls and curves around the eyes and nose. The metal has a rough texture, and the overall appearance is weathered and aged.
