William P. Hall, "The Horse King of the World", of Lancaster, Missouri only advertised a couple times in his career. Here we find in the New York Clipper on April 28, 1906 on page 275, an ad offering his complete circus for sale. ( unfortunately, the microfilms aren't very good sometimes )The Great Wm. P. Hall show toured for one year in 1905 being largely made up of the old Walter L. Main Circus properties. The Pawnee Bill show bought a good bit including four elephants. The Campbell Bros. Shows bought most of the menagerie animals. The rest remained at his quarters.
