Louise Bourgeois’ spiders may be her best-known work (this image from New York Art Tours’ archives captured a bronze arachnid appearing to scale a wall at the American Museum of Natural History), but for 70-years of the late artist’s career, drawing played a key role in expressing states of mind. Hauser & Wirth Gallery’s inaugural on-line exhibition features a selection of drawings from 1947-2007 that channel Bourgeois’ unconscious and personal history.
