You know since we are on the topic of copyright laws here, lets go a little deeper, if we really want to be picky then the artist who made the images of Elvis and Yoda are in violation of those same laws. The character Yoda and his image was created and owned by Lucasfilm LTD, Mr Lucas is not very keen of unauthorized uses of his creations or likeness of his creations without his permission, I have seen it first hand from Lucasfilms staffed attnys. I am sure the "Elvis Camp" may have something to say as well. So.... should we really throw stones here?
Most folks are afraid of heights, me I fear width.
