They also have an active program of exhibitions working with well known artists or their estates. I love when galleries do these sorts of exhibitions. There is something special about a gallery exhibition rather than a museum exhibition. What is that? I have no idea but there IS something.
They work with area artists, such as Thomas Chimes whose work is below, and also release impressive catalogs of their exhibits.
Two of the artists at their booth at Expo Chicago 2012 were Chimes and Louise Nevelson.
Nevelson was Russian but came to the USA at a young age in the early 1900s. She studied at The Art Students League of New York and, unsurprisingly, painted with Hans Hoffman. She was an assistant to Diego Rivera as well. She passed away in 1988 and has been the subject of two retrospectives at the Whitney and a traveling exhibition as well.
