P. M. Sawyer was recorded in one announcement that appeared on June 23, 1854 in the Oxford Democrat (Paris, Maine). A nomadic Daguerreotype Saloon made its appearance here the other morning. Messrs. S. W. & P. M. Sawyer accompany it, and are prepared to take your picture at any time, if you will call on them.
P. M. Sawyer is recorded in Craig’s Daguerreian Registry as being active in 1855-1856 in Calais, Maine. In 1856 he was in the partnership of Sawyer and Robbins. John goes on to say that he is probably the same P. M. Sawyer who was active in 1856 in Norway, Maine.
