Immigrant Photographs
I found these photographs while surfing the net, and have posted them because they are such strong images. They are in the collection of the Library of Congress Prints and Photographs Division (http://lcweb.loc.gov/rr/print/catalog.html), and copies of these and other images can be ordered at the above website. On the linked web page, push the Start button, then search for "immigrants" or another desired search term. The creators and/or publishers are listed below each photograph.
