There's always an element of insanity in Carlos Ruiz's posters. Sometimes it's inspired; sometimes it's just plain weird. This week, he has dispensed with everything but the craziness, and in so doing he has created a piece of art. Sure, it's all but unreadable and therefore fails to do the most basic job we would expect a poster to do—tell us who, where, when, and, in the case of a really good design, give us some idea why—but somehow I don't really care.
