Vintage Cast Iron Frog Bank, Sitting Pose

Vintage Cast Iron Frog Bank, Sitting Pose. Condition is "Used". This is a wonderful vintage bank. It's in very good condition and appears to have its original finish. It has a real nice aging patina which adds to its charm. The piece is best described by carefully examining the photos and asking questions. There is a slight rust chip that has formed under one arm pit that is still attached. There is also a round detail on the back that appears it might be concealing a molding detail or hidden screw. I'm not an expert ... just pointing out what I observe. I can not find a makers mark. The piece weighs 5lbs 10oz. About 7" high x 5-1/4 wide. Again, please use the pics as part of the description. Thanks for your interest.
