Antique Mannequin shoe, woman's single shoe, cast iron made by the Curt fixture co.
These are very rare, and some people think they are door stops, the old mannequin's had wood body, the legs were wood that went into these shoes and were attached by a nail or screw on the bottom of the shoe.
I also have listings for 1 other single shoe for a small child and a child's matched pair. 
Measures 8 1/2" tall, 10" long and  3 1/2" wide.
Really great antique retail collectible.
