Old master paintings come to us with a history of consideration and validation. But what makes a piece of contemporary art a masterpiece? “To find out, ARTnews asked eight people, including art historians, museum directors, curators, and an artist, to discuss what they consider to be the greatest works of three pivotal artists of the last 50 years: Jasper Johns (b. 1930), Andy Warhol (1928-87), and Gerhard Richter (b. 1932). Each focused on one of the artists while sometimes commenting on the others.” – ARTnews
