This is a nice vintage original circa 1920s Zanesville Art Pottery small Horse Planter. I was informed it can be found documented on page on page 252 of the "Zanesville Stoneware Co" reference book by Rans, Ralston , and Russell. With that said this piece measures approx 4-3/4" and in the book they have it as 5-1/4", make of it what you will. The glaze is outstanding. Please see photos for condition. There are no noticeable chips.
