Anotations

Scope note:

Refers to the expressionistic style inspired by children's art characteristic of a group formed in 1948 by artists from Copenhagen, Brussels, and Amsterdam. The formalized group is often referred to as a movement, though technically it is a corporate body made up of founding members, rather than a generalized movement with unaffiliated members.
