Large vintage flower frog. 99% sure it is a Zanesville Stoneware Co. frog due to the runny glaze on bottom and distinctively yellow clay. Nice condition; no chips or cracks, heavy-duty. It looks great in the large ZSC centerpiece vase that is listed for sale! This frog is 4 tall x 5.5 wide x 17 around. These old frogs make unique paper weights and pencil or marble holders too! Age est: 1930's-40's.
