That 1931 picture took me a while to figure out. The view is looking up Brazos Street. The Littlefield Bldg and the Driskill Hotel really stand out. Also interesting are the houses that seem to line First Street (Cesar Chavez) overlooking the river.
I don't remember this video being posted of the University Towers demolition. It wasn't uploaded until a year after the demolition, so that's probably why.
