Martial Raysse is a self-taught artist. His early works were assemblages which included plastic objects. This appropriation of prefabricated materials led to his association with nouveau réalisme, and in 1961 at the Paris Biennale he presented a work entitled Hygiene of Vision, which seemed to parody the shop window displays of cheap articles. Raysse exhibited a world, new, antiseptic and modern. His approach anticipated that of the Pop artists, who likewise used objects and images deriving from advertising. He also created transparent assemblages, enclosing everyday objects in plastic boxes, like a selection of samples of the outside world. He liked to exhibit the object in its own right and in its original purity.
