Some of them were stolen by that Salander guy who ran a gallery and went to jail for accepting paintings to hold or sell---not telling clients he had sold them.....and kept the money.
Robert jr settled the case by accepting $14,000 for 6 of his father's works.
That’s interesting. That’s not a lot of money. This may be why the younger is promoting the elder’s work. Not necessarily because of the money but to create the impression that he is more highly valued as an artist than he truly is.
