Appropriation in art refers to the practice of taking existing images, objects, or ideas and recontextualizing them in a new artwork. Appropriation has been used as a way to comment on and critique various aspects of culture, including consumerism, gender, and race. The use of appropriation in art has been controversial, with some artists and critics arguing that it is a form of plagiarism, while others see it as a valid and important form of artistic expression.
