An interesting website to check out:

Square America
A gallery of vintage snapshots & vernacular photography
(Updated Daily)

Square America is a site dedicated to preserving and displaying vintage snapshots from the first 3/4s of the 20th Century. Not only do these photographs contain a wealth of primary source information on how life was lived they also constitute a shadow history of photography, one too often ignored by museums and art galleries. Or at least that what I tell people- more accurately, the site is a catalog of my obsession with vintage photographs. For the last eight years or so I've spent countless hours digging through boxes of old snapshots at flea markets (mostly here in Chicago and in NYC) and too much money buying photos on eBay. The site is my attempt to create some kind of organizational framework, however idiosyncratic, for the sprawling mess my collecting has created. More importantly, now that the site is up I can tell people that I'm a curator rather than a collector.
