I don't know if all of this have four ribs, but this one does. I'd call it in the blue aqua range. 3/4" chip/flake on the left front (see photo). Similiar but slightly smaller one 180 degrees opposite on the back. Weak embossing on the rear.
Extra pictures available by request. Closes 2pm Eastern Sat Sept 24.
