We’ve seen all kinds of art exhibit promo over the years — printed flyers, Facebook pages, cutesy premiums and miscellaneous schwag — but Smart Crew just upped the ante considerably. To promote their current group show, they painted a New York City subway train.

Due to the nature of this type of stunt, we can’t reveal too many details, except to say that it happened recently. But good luck to the Vandal Squad in trying to figure out who exactly did what. (Photo: Anonymous Source/ANIMALNewYork)
