A new sign has popped up from the Metropolitan Etiquette Authority (aka artist Jayshells), according to Vanishing NY. Last time the artist tackled subway etiquette (you can now buy those signs over at Etsy), and this time around he's targeting texting zombies. Some of the worst sidewalk etiquette criminals around!

We contacted Jayshells for more information on his latest project, and to find out how soon he can get these signs up on every sidewalk—he told us, "there are four different messages" and production should be done next week, after which point you'll hopefully be seeing them around.
