What Happened?

I can't help asking what happened here? I was looking at a new building under construction at Roosevelt & South Komens (4050 West-ish) and saw this across the street; the colorful decay caught my eye.

Garfield Blvd.

A couple of southside buildings: Schulze building at Garfield Blvd (55th) and South Indiana.

Little Niko's at Garfield Blvd. and South Calumet. I have no idea what this was; maybe a little restaurant? It's located a couple of blocks west of Washington Park.
