So there's this really cool comic book artist by the name of Randy Kantz. He's selling some of his very cool artworks in a sketchbook for $15. There were going to be 199 books, but apparently not enough people have gotten the word out. So now there's 99. So if you're lucky enough to have a DeviantArt account, you can get one of these most excellent pieces of artwork.
Check out some of these works of his:
