Please Knock is a New York–based platform dedicated to erotic art through publications, archival material, exhibitions, and in-person events, including the annual NYC Erotic Art Fair — a one-day market and exhibition centered on erotic imagery and underground visual culture.

Founded in 2020, Please Knock began as an online shop specializing in erotic publications and explicit printed material. Unlike most online adult booksellers, Please Knock chose to show uncensored interior pages of the books it sold rather than only covers or censored previews. This quickly led to the business being classified as “high risk” by payment processors and financial institutions, resulting in compliance fees and operational restrictions. Over time, these conditions made the shop impossible to sustain, and it was forced to close.

As a result, Please Knock shifted toward physical events, with the Erotic Art Fair becoming its central annual event.

Among the artists who have participated in Please Knock publications and exhibitions are Larry Clark, Annie Sprinkle, Roger Ballen, Boris Mikhailov, Richard Kern, Mike Diana, Aurel Schmidt, John Yuyi, Joshua Gordon, Heather Benjamin, Ami Evelyn Hughes, Alana O’Herlihy, and others.
 

Additional collaborations include the UK Fetish Archive, housed at London’s Bishopsgate Institute, Vasta Archives, RAM Books, Japanese Avant-Garde Books, and other independent archives and selected bookstores.
