I'm married to a scavenger of sorts and he often totes home rescued boxes of books that I paw through with shiny, hungry eyes. I pull out the odd and interesting and add them to my teetering stack.
I just watched the documentary "Jean-Michel Basquiat: The Radiant Child" and he mentions this book as being one of the best books he's ever read. This is a really stellar book and I have yet to see anyone approach the topic of African/Afro-American Art in the same way since.
