The mall, following a late '70s renovation. The original structure was expanded into a tri-level format, with a third anchor -St. Louis-based Stix, Baer & Fuller- added. The original Upper Level of the mall (indicated in black) became a Middle Level. The new South Wing (in medium gray) had Upper and Lower levels. The basement underneath the circa-1963 mall was, by this time, being used only for storage.
