The New York Public Library has digitized and made available in the public domain, for free, more than 187,000 images. As a graphic designer, I’m not one to shy away from free resources and finding historic images of African-Americans is usually problematic and difficult at best. Plus, if you’re seeking images outside of the USA they got you covered as you can see below. Within their database, using targeted keywords you can find historic images to keep you busy or idle for hours. Thanks to NYPL.
