Membership file contains membership application and resignation. A page from the minutes of the AIA's Executive Committee is appended to the file for context about his resignation. McIlvain was among the Kansas City Chapter members who resigned in 1922 in protest because the AIA Competitions Committee had authorized the Kansas City Liberty Memorial competition to be handled in a different manner than the standard AIA competition guidelines.
