I watched (again) the documentary
Herb and Dorothy. It's too bad that it has no closed captioning and my hearing has become worse than when I first watched it years ago.
But it's a heartwarming story: Rotten Tomatoes gave this short blurb which can't begin to give the flavor of this older couple in their little apartment in NYC, with their cat, and with paintings/drawings literally all over the place, even under the bed.
"The film takes a close look at the historical gift project by the legendary art collector couple, Herbert and Dorothy Vogel, and its impact on art communities around America. Herbert and Dorothy Vogel, a former postal clerk and a librarian, built a world-class collection of
Minimal and Conceptual Art with their modest salaries. Over 2000 works were packed into their small NYC apartment, but they never sold a piece for profit. In 1992, they decided to transfer the entire collection to the
National Gallery of Art, making headlines worldwide. (c) Fine Line
