Modern Art Obsession, a blog well worth visiting and reading, is written by a dedicated collector of photography (Mike, a "youngish NYC Art Collector, working on Wall Street by day, and a total art fanatic by night and weekend" as he describes himself).

"Possibly the best thing about going to Art Chicago this year for MAO, was the VIP program, and getting to see the Richard and Ellen Sandor Art Collection. These events were mostly very well organized
Not only was the photography collection a total knock your socks off MAO WoW.. but Richard and Ellen could not have been more gracious hosts. These walls were filled to the brim with Cindy Sherman, Arbus, Curtis, Prince, Man Ray, Vik Muniz, Penn, Burke-White, Kertesz, Steichen..etc.. they have 2000+ images (and it's almost all on the walls..like how obsessive is that!).. you probably couldn't name an important photographer who wasn't well represented in the collection.
