^That's 823 Congress under construction. It became Austin's first 200+ foot tall commercial office building.
I believe this photo is from 1969. I think that's the Dobie Center under construction in the background there to the left of the Westgate Tower. The Dobie Center became Austin's third 300 footer. Only the Capitol and UT Tower were taller.
Some of the things I notice about this photo is besides the UT Tower, you can also see the Cambridge Tower there. You can also see the Castillian in West Campus.
