Hull Pottery was located in Crooksville, Ohio, from 1905 to 1985. Hull is best known for its pastel matte finished art pottery, especially its Corky Pig Banks.  This piggy bank is a color variation - yellow and blue.  It is in excellent condition and marked on the bottom - Pat. Pend.  Corky Pig USA 1957.   It has the traditional cork in its mouth but I don't think that it is an original one. (The original usually had a metal ring  attached to the cork)

The measurements are:  7 1/2 inches long including cork, 6 inches wide, and 5 inches tall.
