The only reference to the Old Master’s Studio is a number of advertisements in the North Dakota Agricultural College annuals from 1924 to 1929.  The studio was located over the Woolworth store, but no photographer’s name is given.

During the same time period Ernest E. and Raphael E. Baldwin operated a studio located in the same building, but at the address 2 1/2 Broadway. The Old Master's Studio and the Baldwin's studio may have been one and the same.
