Informalism or Art Informel 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 the World War II, similar to American abstract expressionism started 1946.
Outsider art is art by self-taught or naïve art makers. Typically, those labeled as outsider artists have little or no contact with the mainstream art world or art institutions. In many cases, their work is discovered only after their deaths. Often, outsider art illustrates extreme mental states, unconventional ideas, or elaborate fantasy worlds.
