Interestingly there's no pictures of the Rockefeller University or Weill-Cornell Hospital, though they are both clearly there in the aerial photos. The big apartment building Rockefeller housed me in at 63rd and York is a rundown factory at that time.
I think the photographs are all of properties on which property tax is paid. Also, I loved in that building too, when my ex-wife was doing her medical internship at the Animal Medical Center.
