Personal Identities and the Law
I had to go back to the artist and ask that we back the characters even farther away from the true likenesses. All character names were dropped favoring instead to just refer to what the character embraced. Additionally, the artwork needed to be further tweaked.
Thanks to a legal case in California we can use the "Albert" likeness as it is considered public domain now. The court claimed this because it has been over 50 years since his death. Political figures have the "least" rights since they are in the public space already as opposed to an individual. For example, the major of NYC tried to stop his image on the side of a bus and lost.
