Informal art is an art movement that developed in the decade between the 1950s and 1960s and was in opposition to anything that had a form, whether figurative or purely abstract.
A characteristic of informal art, apart from the invention of new painting techniques, was the use of new materials, which the artists considered to be the real protagonists of their works. Alberto Burri’s burlap, plastic, metals and burnt wood, but also the holes in Lucio Fontana’s canvases.
