[edit] Summary
Early twentieth century time clock used to keep track of employee's work hours. Employees would dial the handle to their employee number (1-100) on the face shown here and push the lever. A mechanism inside the box would encode the day, time, and employee number on a punch card. Photo taken in the Artillery Park in Quebec City, Quebec, Canada by Yannick Trottier in 2006
