Metropolitan Etiquette Authority

Situated somewhere comfortably between street art and public service are the amazing signs of the Metropolitan Etiquette Authority. Presenting like a hybrid between an alternate-side parking warning and one of those friendly "mind-the-gap" style helpful hints you find in most subway cars, these pleas for sanity and common decency are ones you wish some city agency was actually producing and plastering all over the city. In fact, they are already fetish objects, "free" limited edition artworks that I suspect are frequently stolen just about as fast as the artist cleverly bolts them to existing signposts. So far, I have resisted the very powerful temptation to stalk one and bring it home for myself, if only because the messages on them so desperately need to get out there in front of the public.

This one is my favorite, so far. Photo spotted, and stolen from, Eileen Costa's facebook page.
