A trio of drawings I have owned for about thirty years---all unsigned, one on tracing paper, the other on heavier paper, and double-sided, the subject apparently Indian Rock, a favorite subject of artists since the 19th century when they visited the Naragansett Bay area of Rhode Island. Perhaps the most famous of the artists who specialized in these scenes was William Stanley Haseltine (1835-1900); his oil paintings of this subject have exceeded $500,000. When I acquired these decades ago in San Francisco I recall having contacted Ben Ali Haggin, New York art dealer considered an authority on works of the artist. He stated these were not works of Haseltine. I recently found these in storage and will list them as decorative works. They are unframed. Measurements are 15 1/4" by 20 1/2". The tracing image fits perfectly over the other work.
