For your consideration is a vintage cast iron pig bank that is marked on both sides: Decker's Iowan. It has a nice darker patina overall and is in very good & vintage condition. (For more information please see page 62 of "Collector's Encyclopedia, Toys-Banks" Published by L-W Book Sales, Gas City, Indiana, copyright 2006.) It is approximately: 2 1/2"H X 4 1/4"L X 1 1/2"W.
