Fine Arts Museums of San Francisco
This striking portrait is not quite a new acquisition, since it was given to the Fine Arts Museums of San Francisco in 2008, but it has only very recently appeared on the internet and does not seem to have been previously documented. The image on Wikipedia was uploaded on 26th September 2017. It was uploaded to "FineArtAmerica" on 30th October 2017 (so now you can buy a La Pérouse tote bag or yoga mat.....).
