The Mutual Musicians Local No. 627 was established in 1917 providing essential services and support for African American jazz musicians. The union helped protect musicians and provide good wages, and performance standards. In 1928, William Shaw was elected president of the union instilling discipline and unity in rank and file. In 1930, under the leadership of Shaw, the union purchased the brick duplex building at 1823 Highland Avenue, near 18th and Vine, Kansas City, Missouri. It was converted into a dance hall and clubhouse, making this building a home for many jazz musicians to meet, socialize, rehearse, and perform with each other. Shaw was expelled as president of the union in 1949 and was replaced by Elmer Payne as president. This photo shows a formal portrait of William Shaw.
