It also sells pieces at art fairs by artists such as Pablo Picasso, Kurt Schwitters, Fernand Léger, Lyonel Feininger, Robert and Sonia Delaunay, Stallone and Fernando Botero.

The gallery works with the estates of Yves Klein, Wifredo Lam, Louise Nevelson, and Robert Indiana among others.

It also arranged for an exhibition of Sylvester Stallone at the Museum of Modern Art in Nice in 2015[2] and hosts the artwork of fashion designer Karl Lagerfeld and the architect Richard Meier.

Between 2007 and 2009, the gallery was involved in a dispute with dealer Asher B. Edelman, who had loaned a work to Gmurzynska that was returned damaged.

Gmurzynska disputed any wrongdoing, stating that "the gallery never received any notice that Mr. Edelman had applied for a default judgment".
