Across the street from the Museum of Modern Art, this show features ephemeral works from more than 35 street artists, including John Ahearn and Stikman; images of the participants’ work (taken by such graffiti experts as Luna Park of the Street Spot, and Streetsy’s Jake Dobkin) arranged in a timeline. The result displays a portrait of the city’s graffiti history from the 1970s to present day.
