Ambisextrous: Gender Impersonators of Music Hall and Vaudeville is a digital collection of materials dealing with the history of theatrical gender impersonation. In 2006, Neil Richards donated a collection of materials related to the history of gender impersonation to University Archives & Special Collections. This collection was originally assembled in connection with his research for his digital exhibition All Frocked Up: Glimpses of Cross-Dressing in Saskatchewan. A special strength of this collection is the representation of performers associated with British music hall and with vaudeville. Ambisextrous was created in 2008 based on that collection and was curated by Neil Richards.
