Augh, this series kicks all sorts of ass. I'm especially loving THE DEAL (Pink Floyd inspired?) and, as always, am impressed by the use of chunky flourished vertical/horizontal lines to keep these stylistically consistent.
I will now make my one very minor criticism, which is very obvious on card XIII: The capital I is a little too similar to the capital X for my liking. I think this could be fixed with literally four pixels of difference, filling in the little chunks at the top and bottom of the letterform.
