I had forgotten about this collection, but I just followed a link to one of its photos. Unfortunately, the owner has decided not to make this images available via Creative Commons, so I can't download a photo and use it here to give you an example. I could have done a screen cap of course, but hey, if they don't wanna share, then so be it.

I linked to a series of Scollay Square photos from the 1950s, but feel free to poke around when you get there. There are many pages that I don't find interesting, but you'll have to see what's there for yourself.
