Sure, you've seen a hundred shots of Katie Holmes celebrating at The New York Observer's 25th Anniversary Party by now. If you didn't know what Rex Reed looked like, now you do. And those pictures of Spike Lee, Mayor Bloomberg and Chuck Close? Sure, we could see how some could be getting a little bit jealous. So this is your final chance to check out the never-before-seen photos (courtesy of Grayson Dantzic) of the legendary bash at the Four Seasons, before this slideshow is lost to the annals of the archives. Godspeed.
