Great DTLA sidewalk shots, ethereal! I used to not be a fan of terrazzo until some years ago, when it seemed to have made a comeback. Now I look at terrazzo floors in old buildings and some of them look pretty cool.
Some then and nows:
Wilshire Professional Building, 1929
USC Archive
Another view from 1929

Same building, from Google Street View

I would like this building if the ground floor weren't so horribly destroyed. Screw Mr. Pizza!
