This document provides an overview of the emergence of junk sculpture and assemblage art in the late 1950s and early 1960s. Younger artists who were dissatisfied with Abstract Expressionism's detachment from reality began incorporating everyday, mass-produced materials into their works as a way to make art more grounded. Artists like John Chamberlain and Richard Stankiewicz pioneered this approach by sculpting crushed automobile parts and other found objects. Their works challenged formalist ideas about color and materials in art. Assemblage and junk sculpture became widespread enough that the Museum of Modern Art held an exhibition on the subject in 1961.
