With locations across the country (the Dallas gallery is the only one in Texas), Martin Lawrence Galleries acquires works from such influential artists as Pablo Picasso, Marc Chagall, and Andy Warhol. The gallery specializes in paintings, sculptures and limited-edition graphics that typically range from the early 20th century to today. Proof that these pieces are museum-quality: Martin Lawrence Galleries has lent some 250 works to dozens of institutions across the United States, Europe, and Asia. When the gallery isn’t in auction season, occasional exhibitions are organized, bringing artists like Rene Lalonde in to mingle and discuss their work.
