Wow, I hadn't even realized that the ad for Lamar Financial Plaza was part of a bigger special advertising section about Austin. (It starts on Page 85.)
Some things I noticed on other pages:
Page 86 - The gold tower that's now Chase Bank Tower still says American Bank on it and you can see the Hobby Building under construction on the far left.
Page 95 - Rendering shows the Four Seasons, One San Jacinto Tower and the never-built Two San Jacinto Tower.
Page 118 - Shows the rendering for the Radisson Plaza Hotel (Now the Omni)
Page 121 - Nice Skyline shot and you can see 816 Congress when it was all white before the makeover.
