I found the link to Square America, described as “A gallery of vintage snapshots & vernacular photography”, while browsing commenter Charlie’s blog, Virile Lit:
I’ve been loving Square America for some time now and want to urge you to check it out. It’s a web site wherein the curator chronicles the history of the U.S. in snapshots he has obtained by combing resale stores, estate sales, and other dusty archives for random, found photographs he then assembles into themed web-based exhibits. The results are simply fascinating. Text doesn’t even enter into it, only the images and you.
It’s a fabulous site that sucks you in as you browse the casual, even amateurish, old snapshots that still can’t help but communicate a sense of time and place. Beyond that, I often found myself thinking, “I almost know these people — and I know I’ve seen those curtains before.” Cruise on over and spend a few minutes going back a few decades.
