1890-1920's "Bird" German Sulfide marble with chalk standing bird figure. Some interior bubbles, polished pontil to back of bird. The marble is in excellent condition. The surface is very good, and does not appear to be polished. One oddity to mention, is an actual 1" long human hair suspended in the marble to the top left. It is not a hairline crack. The marble is 1 1/2" in diameter. It is an old marble, not a reproduction. The collection of antique German sulfide marbles has been assembled over many years of dedicated searching. They can be purchased separately or as a group.
