As the sun rose over Astor Place in New York City on June 2nd, the scene outside of Facebook and Instagram’s office looked something like a cultic ritual honoring the nipple.

Under the direction of photographer Spencer Tunick

, over a hundred people laid on the pavement, women wearing male “nipple pasties,” and everyone covering their genitals with enlarged prints of male nipples—some of the images donated by artists Andres Serrano

 and Paul Mpagi Sepuya

, Bravo host Andy Cohen, and Red Hot Chili Peppers drummer Chad Smith. A collaboration between Tunick and the National Coalition Against Censorship (NCAC), the final photo will be posted to Instagram and Facebook to challenge their Community Guidelines, which infamously ban “female nipples” and restrict photographic nudity. The art action is a part of the NCAC’s #WeTheNipple campaign, which has garnered signatures from over 250 artists, museums, and arts organizations—including artist Betty Tompkins

 and photographer Nona Faustine

, as well as the Leslie-Lohman Museum of Gay and Lesbian Art and PEN America.
