Artist Gives NYC's Subway Riders a Lesson in Manners Poster blitz also targets seat hogs, litterers By Rob Quinn, Newser Staff Posted Apr 21, 2010 10:13 AM CDT 10 comments Comments Subway passengers ride a crowded L train in New York City. (Getty Images) (Newser) – Call him the 21st-century Emily Post: Artist Jason Shelowitz is out to teach New York City subway riders that groping, sneezing, preaching, and littering is totally uncool. Shelowitz quizzed passengers on their pet peeves and made the top 10 into pretty humorous posters in the style of the transit authority's own, Gawker reports. He's been plastering them throughout the system this week. "Nail Clipping," is the theme of one poster. "Under no circumstance is the subway the right place for this. The sound is incredibly annoying and the little nail bits go flying all over the place. Keep it at home, please. It's crazy that this even had to be mentioned." Have a look at the full set of posters here.
