By 1952 Marlborough was selling masterpieces of late 19th century including bronzes by Edgar Degas and paintings by Mary Cassatt, Paul Signac, Claude Monet, Camille Pissarro, Alfred Sisley, Auguste Renoir, and drawings by Constantin Guys and Vincent van Gogh.
[citation needed] In the late 1950s and early 1960s, Marlborough put on a string of exhibitions related to expressionism and the modern German tradition: "Art in Revolt, Germany 1905–1925", "Kandinsky, the Road to Abstraction" and "The Painters of the Bauhaus".
During the 1970s and 1980s, Marlborough staged exhibitions by Frank Auerbach, Lynn Chadwick, Lucian Freud, Barbara Hepworth, R. B. Kitaj, Ben Nicholson, Victor Pasmore, John Piper, Graham Sutherland, Jacques Lipchitz, René Magritte, Max Beckmann, Max Bill, and Henri Matisse.
During the 1980s and 1990s, exhibitions of work by Stephen Conroy, John Davies, Bill Jacklin (artist), Ken Kiff, and Paula Rego were held.
Another retrospective exhibition of Rego's work, curated by Marco Livingstone, was shown at the Museo Nacional Centro de Arte Reina Sofía, Madrid, in 2007.
