Focus on this artwork and explore the Appropriation and fair use.
Warhol is regarded as an artist known for the appropriation of images and he often made use of publicity photographs and publicly available photographs and motifs not owned by him, which often brought him into conflict with the owners of the source material.  An example of this is Warhol's Marilyn series including the Marilyn Diptych, which resulted in a settlement with the owner of the Marilyn Monroe publicity photograph which he used as the source material for the paintings. Warhol and his estate have settled many copyright disputes including with regard to his famous flowers paintings and paintings of Jackie Kennedy, as discussed in detail in "Andy The Appropriator: The Copyright Battles You Won't Hear About at The Whitney's Warhol Exhibit" from The Columbia Journal of Law & the Arts: "Although some of Warhol’s work was commissioned by individuals or companies, much of it was appropriated from other artists, photographers, and brands. Two of his most famous pieces, Marilyn Diptych and the collection of Campbell’s soup cans, are examples of his habit of appropriation. For the Marilyn series, Warhol took a promotional photograph of Marilyn Monroe and transferred it onto silkscreen print using different colors. He did not own the promotional photograph that he used and he did not have permission to use it. The resulting work was transformative enough that a strong fair use argument could be made today, but Warhol’s appropriation is undeniable. Similarly, Warhol used the Campbell’s Soup logo without permission from the company for dozens of silkscreen prints. Eventually, Campbell’s Soup tacitly approved of his use because of the free marketing they were receiving, but Warhol’s use of their logo without initial permission was still appropriation."
