Marie Duval: Maverick Victorian cartoonist offers the first critical appraisal of the work of Marie Duval (Isabella Tessier, 1847-90), one of the most unusual, pioneering and visionary cartoonists of the nineteenth century. Duval's cartoons, strips and illustrations revolutionised print comedy. Her London characters became a mainstay of Judy magazine, a rival to Punch, and introduced its middle-class readers to a lower-class milieu - domestic servants who get the better of their masters, street urchins who terrorise the elderly, clowns who are miserably unfunny. The most famous character was Ally Sloper, a boozy ne-er do well, always in trouble with the police, the landlord, and his wife - developed by Duval into nothing less than a national hero. The book discusses key themes of Duval's vision and production, relative to wider historic, social, cultural and economic environments. It identifies her as an exemplary radical practitioner, especially significant for importing ideas from the stage to the page, and for confounding gender expectations. She emerges as a key figure in the new congruence between performance, illustration, narrative drawing and novels. The book is a journey of rediscovery, sourced from an unprecedented range of primary sources and bringing together the fields of Comics Studies, Theatre Studies, Comedy Studies, Periodical Studies and Women's Studies. It aims to restore the maverick Duval to her rightful place in history.
