In the winter of 1993-94, photographer Merry Alpern began taking photographs from a friend's window off Wall Street in New York. Looking out, two windows opposite the apartment looked inside an after-hours sex club, "where stock-brokers and other well-todo businessmen handed over hundreds of dollars and drugs to women in G-strings and black lace."

Using a telephoto lens, Alpern captured everything from blow jobs, strip teases, and drugs to women rifling through clothing racks and trying on bathing suits. In 1995, she, Andres Serrano, and Barbara DeGenevieive were all rejected and vilified by the National Council of the NEA for their work. While many viewers were made uneasy by the voyeuristic images, Alpern's work can be found in museum collections.
