I notice that, as in previous tracts, Chick's Devil has the traditional horns and goatee. That's one of the more recognizable and interesting appearances for Satan, but I can't imagine it would normally be that effective for tricking people. There have, of course, been a lot of different conceptions of Satan over the years, from a suave intellectual to Dante's hairy three-headed monster. Nowadays, it seems like the Devil is often portrayed as a sleazy used car salesman type, which seems rather demeaning for a guy who's sometimes credited as ruler of the entire material world.
Anyway, happy birthday to revme, and to themall!
