The Haggerty-Cook Piano Company was a small manufacturer in Warren, PA during the 1910-1920 era. The firm built upright pianos and player pianos during the height of the player piano's popularity. They were known for building a higher grand instrument, and they had a good reputation in the industry. The firm never built pianos in large volume, and they are a bit rare today.
