The ad has a typo. It was Dr. Kelley's Museum. Apparently Morris DeWitt Kelley was born around 1878 and raised in the Covington, Kentucky area. When he came to Washington and applied for professional physicians license in 1906 he was denied, so he opened this "museum" in Spokane.
He left Spokane around 1914-1915 and returned to Kentucky. Eventually he made his way to Birmingham, Alabama, where he died as the result of a fall in 1942. At the time of his death he was recognized as a medical professional.
