Rare WADE of England green frog piggy bank

Rare and whimsical green frog piggy bank is marked "WADE ENGLAND" on the bottom and is believed to be made of porcelain. The frog has droopy, sleepy eyes, a tilted head, and a sly grin. The shiny glaze is sort of a jade or moss green. The coin slot is on his/her back, and the hole to retrieve the money is on the bottom with a plastic cap. There is one small (1/4") horizontal chip at the base of the frog's left leg. In my opinion, this is not very noticeable at all (see left-facing photo) and does not take away from the piece--otherwise, this decorative and functional piggy bank is in excellent pre-owned condition. Approx. dimensions: 5" H (eyeball to toe) X 4.5" W (knee to knee) Tags: animal, toad, nature, amphibian, collectible, collectable, Wade whimsies, English, British, pottery, smile, smiling, fairy, whimsy, gift, child, nursery decor
