Excuse this if it's already been posted, but I just recently ran across an awesome photography site with some really great photos of Reed, Cale, Nico, and many denizens of the pre- and post-punk scene in NYC (among others). Apparently some of Ms. Chernikowski's photos were used in the book, "Please Kill Me". But it's worth checking out the whole folio if you haven't seen it already. Enjoy!
