So, I just took a look at the Hillary Clinton book via Amazon and apparently, Bluewater didn't think it was necessary to credit me for my artwork.
Thankfully, my signature is still visible on the front, but there's no mention of me on the inside cover… which means I can't send it in as proof that I'm a published comic book artist when I attend conventions.
Unfortunately, there's not much to be done at this point, since it's already been printed up and I doubt there'll be a second printing. Even so, it's still a jerk move on their part.
Just one more reason that I won't be working with Bluewater again.
