An original stone lithograph is hand drawn by the artist on limestone or marble. The process is difficult and remarkable when one realizes the fact that the image is drawn backwards, so that when it is printed it is correct. Each stone is used to print one color and the best stones, which are Bavarian limestone, are grey in color and have a clear complexion free of fossils and other flaws. These stones are becoming increasingly rare. After the edition (number of impressions) is hand-printed, each impression is signed and numbered by the artist. Imperfect impressions are destroyed and the stones and plates are effaced, and each edition is carefully documented. This is the oldest lithographic technique and is still considered to be the best by some.
Please note: Bill has done two Stone Lithographs, entitled, Breaking Horses and Saddle Horses and Broncs. One of these days, as time permits, the handful we still have may be offered.
