I just came across this and had to share. I only states that its a prop firm in Chicago - and apparently one that has done extremely well. What an amazing place to come to work to everyday! http://www.interiordesign.net/slide...eff_Weber_Photography_by_Michelle_Litvin_.jpg
I'm not sure that is a prop firm. It looks kind of like Citadel. But they are on Dearborn, not on the river with that view of the bridge. I also thought BAM. Maybe Bone will chime in here. He has been in a lot of the firms here. Looks like they are on Wacker Dr.
Speaking of nice prop firms, these guys have a nice setup in the west loop. http://mntrading.com/facilities/#fileadmin/templates/images/facilities/photo-building-night.jpg
The photo of the defunct bridge is from a window of the chicago sun times building which is also confirmed by the building across the river with the little circlular windows. So, what firms are in that building, GETCO? Vankar? Idk..
Could it not be the Montgomery Ward Building? That building is massive and does have a lot of trading firms there. It's on the water and you could probably see that bridge from one of their windows.
