Sun Drug Co Warehouse - 06/28/1946

I have no idea where exactly this is, but my gut tells me it may be the Terminal Building that sits on the Allegheny between Station Square and the SouthSide proper.

Olver Avenue 05-20-1948

This shot is of Oliver Avenue between Smithfield and Wood taken 05-20-1948.  The block is mostly covered by the backside of the First Presbyterian Church that houses the top notch eatery Franktuary in its basement.

Bob Walk 1992

Ohh Man, look at that epic mustache/struggle. 

PGH Skyline 198?

Not sure exactly when this pic was taken, but with PPG being there and 5th Ave place not, i'd peg this sometime in the late 80s
