Such an item is this "What Can Satan Do For Me?" pamphlet that I snapped up a few years back from a stack in an East Village watering hole. I have been unable to track down its provenance, and I have yet to discover what the Order of the Waning Light referenced in here might be, but as a parody of similar Christian Mission handouts, I think this is pretty successful. I also like the weird Mark Ryden-esque drawings used here--creepy kids and demons: two great tastes that taste great together!
