Me too. Who would have thought they were these great collectors? I guess, their artist friends :)
I only recently found out about Serrato, and his story was inspiring because he's a local. I grew up a few miles from Whittier, within the range of what might be called "the greater eastside" of LA, which extends from downtown Los Angeles to the Orange County border, and is majority Chicano. It's a vast working class and middle class (and some wealthy) area that's largely Mexican American, and was the urban center of the Chicano Movement of the 1960s and 1970s.
I heard he's selling off parts of his collection to pay for his retirement. My feeling is, "good for him!" He probably gave up a lot of his savings to buy art, and now, his past support's going to help him live out his life.
