The Best Sign in the History of the World
Or a contender, anyway. It's in the subway at 14th Street and Eighth Avenue, disguised as an official Metropolitan Transportation Authority notice -- except that the MTA generally doesn't do numbered screen prints. Artist Jason Shelowitz does.
On this poster, evidently part of a campaign he's waging (of which I knew nothing until I saw the sign this evening and burst out laughing), Shelowitz has replaced the customary MTA logo, in the lower right-hand corner, with one for the MEA; the "E," of course, stands for "etiquette."
His etiquette rant may not be in the official style of the MTA, but it's definitely in the style of a conductor or two. It will have a lot of people who've been creeped out by their fellow subway riders saying, "Hear, hear." Or, as someone's already scrawled on this poster: "Yes!"
