Final answer:
Appropriation is when an artwork uses another artwork as its subject matter, often to create a new work that challenges concepts of originality and ownership.
Step-by-step explanation:
When one artwork takes another artwork as its subject matter, this is called appropriation.
Appropriation in art is a process where artists use pre-existing objects or images with little or no transformation applied to them.
It is a concept that involves the recontextualization of art to create a new work.
The act of appropriation can challenge notions of originality and ownership in art.
Unlike abstract art, which involves forms that do not seek to represent reality, appropriation directly engages with recognizable imagery from other works.
