Take a look back in time to the early 1900s with this photo of a policeman standing guard at the entrance to the White House, taken by Frances Benjamin Johnston.

In 1919, the Prince of Wales visited Washington, DC. This video shows his tour of the area.

This is a rare and unique glimpse back in time to 1926. The photograph from the Library of Congress shows four adults and six children from Passaic, N.J. protesting wage cuts in the textile industry outside the White House. It's definitely not something you're likely to see these days!
