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’s what I tell people- more accurately, the site is a catalog of my obsession with vintage photographs.
