Thievery Corporation concert poster by EMEK. But to call it a poster doesn't do it justice. First, it supposedly has a tracking device to discourage resale. Second, it's screen printed on clear plexiglass. You can see it animated here, to get a better sense of the fact that it's printed on plexiglass.
