Interesting family, interesting art collections... This is one I'd like the catalog/book for, if not to actually get there to see it.
I'm interested in other art besides that of the impressionists and others mentioned, meaning I don't restrict myself to that, but my heart is still made to pitty pat at the lists in this article - oh, and the click on to enlarge photo of the Renoir, At the Concert, a painting I'd not seen before.
I used to not like Renoir; have gotten over it since I saw one - Luncheon of the Boating Party - in person at the Phillips Collection. I love even the photo of 'At the Concert'.
