From Poland, With Art

     So, the walls go up and your artists are locked in.  What to do, what to do.... They're a subversive lot, artists; many of them don't even understand national borders and they've got to be kept busy....

     Let's ban imported movie posters and make our own!  And thus arose the Polish School Of Posters, which promptly began leaking influences back across the borders and left room for artists to sneak subtle snark into their work.

    Can't stop the signal.
