This publication explores the artistic work of French painter Claude Viallat, focusing on his iconic use of tarpaulin (bache) as a canvas and motif. Produced in association with the Centre Georges Pompidou, the book documents Viallat’s experimental approach to form, repetition, and color through stenciled patterns on unstretched fabric. It highlights his role in the Supports/Surfaces movement and includes visual analyses of his process, where shapes and counter-shapes interact dynamically across surfaces. The volume serves as both a monograph and an educational resource, reflecting on how everyday materials are transformed into expressive art. Richly illustrated, it offers insight into Viallat’s influence on contemporary French abstraction and his ongoing dialogue with space, structure, and perception.
