As theater exhibition increased during the 1920s, theater owners went about making changes to their theaters; adding more seats, hiring more help, etc. For John Hamrick, owner of the Portland Blue Mouse theater, installing a new, custom designed Wurlitzer organ was just the trick. According to an article in the Oregonian, Hamrick had the Hope-Jones Wurlitzer organ installed at the local theater in the spring of 1922. As the first of its kind in the city, the new organ, on its own, was sure to stir up some attraction.
