As far as I remember, the sculptures were only on the 105th floor. Cantor's other office floors were generally bereft of special appointments, and rather spartan compared to the executive area.
I can confirm that Cantor (and their associated companies, including eSpeed, Cantor Gaming, etc.) occupied floors 101-105. However, they did share floors 101 and 102 with other companies. Cantor took up approximately 40% of the 101st floor, and that floor was shared with Kidder and Peabody and a small non-profit. On the 102nd floor, Cantor occupied half of the floor, and that was shared with a Japanese bank (name escapes me at the moment), and Alliance Consulting.
I didn't go up to Windows all that much, but occasionally myself and the rest of the Marsh IT department would occasionally go up to Greatest Bar in the World for happy hour. I wasn't a huge fan of the place because it was so damn expensive, and quite honestly, I was always fine with drinking at (insert random hole-in-the-wall-bar name).
Actually, on September 7, 2001, the last day I was ever at the WTC (the day before I got on a plane to fly to San Diego to attend my dad's Navy retirement ceremony, and hence why I survived the attacks), we had dinner and drinks at Windows. And that was the last time I ever saw any of my colleagues. All but one was killed in the attack, and I suspect it was when the plane struck because their desks were on the 96th floor on the North face of the building, right where the plane impacted. Had I been there that day, at my desk on the Northwest corner of the 99th floor, well, the wing sliced through that floor, but I don't really want to speculate.
Yeah, I'm sure the place was insanely expensive. I bet it was neat to see the wide windows at WOW after working in offices with the narrow standard 18 inch windows. I've read that a ton of Cantor employees would go up to Windows after work given that they were just below it, so I was wondering if that was a habit amongst MMC employees as well.
MMC operated a small chunk of 93 on the south side, correct? The rest of that floor was occupied by Fred Alger, who had extremely lavish offices decorated with marble. I found an article from 1999 interior design magazine about the renovation of Alger's offices that includes pictures and they were indeed very impressive looking. I'll see if I can find it.
