Since this seems to have turned into our annually re-occuring Calgary nostalgia thread:
Market Mall original and first expansion
Southcentre 1974 (looks the same as today!)
A Woolco at a Calgary mall somewhere in 1975? Westbrook?
The Simpsons Sears signage at North Hill which explains why all those brick lines are there and why the Sears logo didn't fit
Chinook North and South malls?
TD Mall / Original Devonian Gardens - what an amazing childhood place with all the maze-like paths and nooks and crannies and jungle gym hidden in a dip under the second level
