Porcelain ponies are my favorite subcategory to collect. I'm always looking for them with colorful and unusual glazes. I'm also looking for a U-4 Fred Locke with an underglaze ink marking on the skirt, a Light blue U-11C Pittsburg, a yellow or green U-14A, U-14B in dark green and a U-39 Fred Locke marked on the skirt to name a few.
