Informalism
Informalism or Art Informel (French pronunciation: [aʁ ɛ̃fɔʁmɛl]) is a pictorial movement from the 1943–1950s, that includes all the abstract and gestural tendencies that developed in France and the rest of Europe during World War II, similar to American abstract expressionism. Several distinguishing trends are identified within the movement such as lyrical abstraction, matter painting, New Paris School, tachisme and art brut.
