The Artist and His Model, Dean Cornwell
This beautiful piece by the brilliant American illustrator Dean Cornwell was in a private collection for years, and was sold at auction last October.
The Heritage Auctions site has details.
For those who don’t have a Heritage account, you can see the image in high resolution (2.8mb) through the link above for a Russian blog. I’m otherwise unfamiliar with the blog, so surf with that in mind.
