(a blending of the phrases "New York" and "Puerto Rican"). The landmark Nuyorican Poets Café is a bastion of the Nuyorican Movement, an intellectual movement involving poets, writers, musicians and artists of Puerto Rican descent, mostly notably the late Pedro Pietri and Giannina Braschi. While the state has an official poet Laureate, New York City does not. Instead, by tradition it hosts an annual "People's Poetry Gathering", curated by the City University of New York and city poetry groups, in which ordinary New Yorkers offer their own lines to an epic poem for the city. This technique was also used in the creation of a spontaneous poetic response by New Yorkers to the September 11, 2001 attacks that became a travelling exhibition called Missing: Streetscape of a City in Mourning. The poems, with 110 lines each for the 110 stories of the destroyed World Trade Center towers, were printed on black, billowing cotton banners over in height.

Immigrant culture in the city was the central topic and inspiration for comics from the days of Hogan's Alley, the Yellow Kid, The Katzenjammer Kids and beyond. Virtually all creators and workers employed in the early comic book industry were based in New York, from publishers to artists, many of them coming from immigrant Jewish families in the Lower East Side and Brooklyn. It can be argued that superheroes, the uniquely American contribution to comic books, owe their origin to New York, despite the fact that the first superhero, Superman, was created by two artists from Cleveland, Ohio. Even when not based explicitly in New York, superhero stories often make use of recognizable stand-ins for the city, such as Metropolis or Gotham City (Gotham being a common nickname for New York). The form and narrative conventions of superhero stories frequently dictate New York-sized cities as the settings, even generically. Marvel Comics became famous for breaking with convention and setting their stories explicitly in a "real" New York, giving recognizable addresses for the homes of their major characters. Peter Parker, Spider-Man, lived with his Aunt May in Forest Hills, Queens. The Baxter Building, long-time home
