Art on the Subway?

Yesterday morning at 5:30 AM I went with Ken to take photos of him putting up art in the subways. He's going to see the reaction he gets from these posters. He's posted them where real ads would go. The posters all have a message. We put up 3 today. We rode with them to Jamaica Queens and back to Brooklyn. Only one was taken down, either by the MTA or a passenger. I'm hoping to snag one of these orginal pieces. So far he's only putting them on the F train, which is my train.
