Mason & Hamlin Piano Company, New York, N. Y. Gentlemen: The Mason & Hamlin Piano used by me during my operatic engagement in this country has been a source of great pleasure. Its beautiful singing tone is remarkable. Such qualities for the vocalists or pianiste must be a great inspiration. I know of no piano that gives me so much satisfaction and heartily recommend it to those of my profession. Mason & Hamlin should feel proud of their great achievement in producing those wonderful instruments.
