UHL ??Pottery pig/piggy Bank

Up for auction is this vintage wonderful UHL??, piggy bank I have been ...told. Unmarked. It is in great condition, but one of his front feet has an open hole. I honestly cannot say if it came that way or not, perhaps someone can help me out on this. The pig is 5 inches from snout to tail, and 3 1/2 inches high and 4 inches wide. He is an off white "pottery" white color. He is lookiing for a home with possible other piggy banks to keep him company!
