Pictured is a quite small sponged-decorated yellow ware pig offered for sale.  The pig is sponged with a combination of dark olive green & tan over the entire surface.  It measures 3 1/2" in length, 2" in height, & dates from 1895 - 1920.  It's in excellent condition with but a tiny pin head size nick at the coin slot, seen as a tiny black dot, otherwise perfect.
