I was at Barnes & Noble yesterday, looking through her new book "Exposure," and ran across this image. It was identified as Spanish Gypsies, but unfortunately no additional information was given.
This is an incredibly intense book, and there is an appendix where she discusses many of the individual photographs, in particular Tiny and Mike, two of the children from her beautiful but gritty photoessay on street kids in Seattle.
Her work certainly reinforces what they say on Malcolm in the Middle, "Life is Unfair."
