Post-1960s art rejected the institutional hierarchy of materials and objects

Evidence

The new artistic approaches are detached from those approaches instituted by the history of art. They build their own system of values, mainly based on freedom of creation: any material can be conceived as artistic material, any object can endorse the role of the work of art, any image (reproduced or reproducible) can become a visual reference, any action can be considered a form of artistic expression, whether or not it falls under a reduced or expanding space-time constraint, and in spite of its transitory character. — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 2912
