J. Paul Getty did not collect drawings. In 1981, however, the Museum purchased a Rembrandt chalk study, Nude Woman with a Snake. The Drawings Department, established in 1983, oversees a collection strong in old master works. Drawings survive in greater numbers than paintings or sculpture, so it is possible to acquire examples, like Michelangelo's Holy Family, by artists whose work would rarely be found on the art market otherwise. Since the early 1990s, the collection's focus has shifted toward acquiring drawings from the 1800s and 1900s, including a Degas sketchbook.
