I already know about the Copywrite and the right use of someone else’s work when designing a poster for clients or businesses. In the past, I have used another’s creative work, but I always have to read the creator’s rights if they allowed us to use it for personal or commercial. I also have to look up for a websites that allowed free material for me to use for the project.
Fairey should have to look for the original image and see the creator’s contract. It’s fine to use the photograph for references, but he edited the original photograph and traced it, which is a big red flag.
