Antique Vintage Large Primitive Cast Iron Frog. Very nice old cast iron frog that was probably made as a door stop in the late 19th century. The frog’s head is tilted up slightly. It measures 7.5″ long x 7.5″ wide. It weighs almost 4 lbs. Retains old dark green paint. Looks like the bottom was repainted. No damage or breakage.
