Lots of neat Professor Layton vs. Ace Attorney art, including “Dark Layton”
NE: "The last time we posted something from the Professor Layton vs. Ace Attorney art book, we were treated to some interesting “Dark Phoenix” art. Now you can have a look at “Dark Layton” (picture 14) and a whole bunch of other neat stuff."
