A clean fresh copy of the attractive book "Masters of Light/Plein-Air Painting in California 1890-1930, published 2002, by the Irvine Museum. This First Edition (stated) copy is signed by both Joan Irvine Smith, and Jean Stern, two figures featuring prominently in the promotion of California plein-air paintings in the past thirty or so years. Smith, who passed away in 2019, was a socialite and philanthropist, with deep roots to Southern California (as in, the Irvine Ranch); Stern, an art historian, longtime dealer in fine art and shepherding its development since the early 1980's (he is credited with actually developing the term "California Impressionism). The long professional relationship between Joan Irvine Smith and Jean Stern is detailed in a wikipedia page. The renaissance of interest in California impressionist art began in the mid 1980's, with Smith actively promoting the school, leading eventually to the establishment of a museum in Irvine.
