@Kyeh Um, yeah. I get parody when you use a style like that to make, say a Star Wars scene making them into those characters. Something that is reminiscent of, but clearly not the originating artists’ work. But the one you’re referring to (I think) is basically traced art with masks placed on top of them.
I’m with you in that I think that goes well beyond parody/fan art/artistic license and more into the the realm of infringement. Unfortunately (or maybe fortunately for the artist), Woot seems to be a lot more lenient on this type of thing. I guess we’ll see what they think if it actually makes it to print, but they simply don’t disqualify shirts from the derby like they used to.
