Milk Glass Bull's Head Mustard Jar which was made by Atterbury Glass in the 1880's. This one has wonderful Opalescense and is marked PAT APLI FOR. It is 4 1/2" tall. This one does have a broken horn and there is a flat flake on the side of the base. The inside rim which fits down into the base has chips on it due to it's use over the past 120 years. You cannot see these chips when the lid is in place. He is a nice shelf piece at a really great price for this hard to find piece of history.
