Need Help Locating These People

This is a fold-out poster of talents that were part of Lennie Barin's modeling agency in early 70s NYC. Christa is among them. Some of these models are from the Andy Warhol crowd. I'm trying to find out if any of these people are still alive. If anyone out there knows one or more of these - and more importantly, knows their current whereabouts - please let me know. (You'll probably have to zoom in on the pic to see everyone clearly).
