Did you like working there?
Ps I also worked in a phone exchange building. Cool thing was that there were half floors. 1, 1 1/2, 2, 2 1/2 etc. These floors were in fact half height like in the movie Being John Malkovich. Except there were no offices, they were used to route the huge cable trunks between floors and rooms.
These days with single fibers replacing thousands of cable pairs I'm sure they're a lot more roomy than they were back then.
You'd want to glance inside ex-AT&T 32 Ave of Americas for the full art deco.
That's a great story about the half floors!
That's how I ended up working there. 33T used to be packed full of gear but everything shrank so much that AT&T found themselves with dozens of empty floors. They didn't renew a lease on a big NJ lab I worked on, and a number of us ended up being able to choose commuting to NYC.
