This thesis redresses the lack of scholarly attention paid to painted circus banners produced in the United States during the first half of the twentieth century by exploring the extent to which American folk art painting scholarship, methodologies, and objects can be used to articulate the meaning and significance of banner painting. This study expands the disciplinary treatment of banner painting by introducing domesticated art as a means of representing non-academic art produced in the U.S. The thesis also presents a model for exploring banner painting after identifying traditional American folk art painting methodologies, which fail to investigate banner painting style, format, and artistic training associated with banner work.
