I'm replaying through Arkham Asylum again, and in the Penitentiary, there's multiple cells. Right off the bat, you find Calender Man's cell, then find Two-Face's and Freeze's cells. But I got a question for those of you who know. All around, there's cells with drawings on them. Can anyone identify who they belong to? I think I may have found Quinn's cell, due to a Joker smile and a Batman. I also think I found Penguin's cell, due to writing that says 'Welcome to my humble adobe'. They also say you can find Black Mask's cell, but I haven't found it yet. So for anyone who knows, can you help?
