King of Prussia Plaza
King of Prussia, Pennsylvania - circa late '60s
This is a section of the original King of Prussia Plaza, not the 1981 Court at King of Prussia addition that was added across the street, as a walkway-connected part of this two-building mall complex (similar to Somerset Mall, in Troy, Michigan).
There's a decent history overview of this mall at Wikipedia below, and also the aerial link I've provided is quite spectacular--especially the bird's eye view option! Be sure and take a gander at it.
