The 3rd Street "Glass Hallway", as it appeared in the late 1960s. In this view, we see the north end of the corridor, with the 3rd Street entrance in the distance. Some years earlier, the leaky skylights above had been covered with tar paper and shingles, making the interior dark and foreboding.

Another late '60s-vintage snapshot; this a reverse view of the area seen in the photo above. Note the "Shopping Center" sign that had, more than likely, been added as an enticement to lure customers away from all of the new-fangled, suburban shopping options in -and around- the "Gem City".
