Matthew Petz Sketchbook (2011) Remarque by Matthew Petz [Ferret with turtle on head]

I do not know if these characters have names, but I am a lover of animals, and I also go in for anthropomorphized animals in comics, so I'm sure that's why I wanted this sketch. I have a feeling that the story about these characters did not yet have a physical form that was available for purchase though, so I haven't read about them and don't know anything about them. I just bought the sketchbook from Matthew and had him sketch the cute animals on that. Go figure. If anyone happens to know anything about these characters though, I'd love to hear more about them! I got this at the same con at which I got the Night Owls book remarked from the Timony Twins.
