After seeing Matterhorn1959's slides of the Hills Bros. Coffee House, I remembered this slide (dated January 1959). It's not the most exciting photo in the world, and the view of the Hills Bros. storefront is nowhere near as good as his. But if you look to the right you can see a rare view of the temporary "construction wall" announcing Liberty Street, "Grand Opening 1959". It really does seem odd that they had so many plans for this area and yet not a single nail was hammered home (as far as I know). Did the park's guests wonder why this construction area was so mysteriously quiet? I've seen photos where the sign announces "International Street" (Grand Opening 1957), and I'm pretty sure there are photos with "Edison Square" as well.
