Driving Pony Slide /Brooch Our prize pony with driving tack. Complete with blinders and bridle, this piece measures 1 1/2 inches round. 2 loops on the back allow the design to hang evenly. A pin back also allows this to be a brooch. This is a solid, heavy-weight piece, as the back is not followed out. Available in Sterling Silver or our Rose Bronze. Arrives with an 18-inch black leather neck cord.
