When I visited the Fisher Collection at the San Francisco Museum of Modern Art a few days ago I particularly noticed three enormous canvases with pigment applied on top of vast fields of honey-colored resin. Their shiny surfaces made them impossible to photograph under the gallery spots, but I later came home and poked around to see what images I could find by the German artist who painted them, Sigmar Polke. I also discovered that he had only just died, in June of this year, at the age of 69.
