Flying pigs

No idea what this poster is for, its one of a series near Heuston Station in Dublin. I think its a nice poster and a nice image.

I'm sure there's a Pink Floyd album with Pigs flying over Battersea Power station which probably inspired this image: the album cover was created the old hard way with film images, by Psygnosis I think. This one took a split second on the way to a meeting.
