Wooden case with a blue background containing twelve squares of wadding.

After a start with space or nuclear research, Manzoni turned to the informal and then turned to work on the Achromes which began in 1957. In 1959 he was one of the founders of Azimuth and began his most provocative phase, of demystification of art: from 'breath' to artist's 'shit', to hard-boiled eggs signed with the thumb, to flesh and blood models signed by Manzoni. Achrome is a conceptual work of art that arises from a provocative intent that has its roots in the Dadaist reflection of demystifying the artistic object. Here the wadding squares of the work, just as the title suggests, appear white because they are naturally achromatic, devoid of color. Achrome was exhibited at the 1st Biennial of the Progressive Museum of Contemporary Art in Livorno together with the two Assessment Tables.
