Free vintage printable images

Vintage Printable is a fascinating (though difficult to browse) archive of vintage photos, illustrations, and page scans. Files vary in resolution and the usage restrictions are a bit murky; most state "image in the public domain believed to be free to use without restriction in the US." I wouldn't build a corporate ad campaign based on "believed to be," but you could certainly make yourself some wall art, desktop wallpaper, or fun projects for personal use. Via Curbly.
