Lehmann Maupin Gallery(as in Rachel Lehmann and David Maupin) is a contemporary art gallery in Manhattan’s Chelsea neighborhood founded in 1996. Their Chelsea location is one of two they now have in NYC; they also have a Hong Kong branch. They represent artists working in a variety of media, and their current NYC exhibits(in Chelsea and Chrystie St.) feature the important LA-based photographer Catherine Opie, known for her work with LGBTQ topics. The Chelsea installation(through 2÷20÷16) is called Portraits and Landscapes; the former being formal pictures of famous people while the later are abstracted views. Both are worth seeing.
