Frog Skin Green Glazed Terracotta Frog Playing Instrument marked on bottom. There are no chips/cracks. The bottom appears to be marked with possibly JGD. I went over the area with a pencil to try and get a better picture, but I am still unable to make it out for sure. I did clean the pencil marks off afterwards. This striking frog measures 8" tall, 4" wide, and 5" deep.
