The end of the year—always a time for reflection. So we thought we'd dig in to the archives of Serious Eats site A Hamburger Today and bring you some images worth highlighting again. They're from the Library of Congress Prints and Photographs Online Catalog and offer a look at the early days of the hamburger.

Most of the photos here were taken by Russell Lee (right; 1903–1986), who was invited to join the federally funded Farm Security Administration as part of a team of photographers charged with documenting the plight of the rural poor during the Depression. (Esther Bubley, Jack Delano, and Arthur Rothstein, whose photos are also represented below, were members of the project as well.)

These photos are truly a fascinating scrapbook of hamburger—and American—history, and they're available for reproduction online at the Library of Congress Prints and Photographs Reading Room (search the catalog for "hamburger"). Dig in!
