Shorpy.com is a photo blog about what life a hundred years ago was like: How people looked and what they did for a living, back when not having a job usually meant not eating. We’re starting with a collection of photographs taken in the early 1900s by Lewis Wickes Hine as part of a decade-long field survey for the National Child Labor Committee, which lobbied Congress to end the practice. One of his subjects, a young coal miner named Shorpy Higginbotham, is the site’s namesake.
