I’ve mentioned in the past that high-end auction sites, like Sotheby’s, Christie’s and Bonham’s often have online auction previews that feature nice large images of museum quality artworks (as do their listings for past auctions.)
The upcoming 19th Century European Paintings auction at Sotheby’s for July 9, 2019 is a case in point, and features works by a number of notable artists.
