Bulldozer in the White House

This photograph shows the interior of the White House completely gutted with a bulldozer in the foreground. Visible are the steel frame towers built to support the third floor and the roof while the rest of the house was demolished. One of the steel beams has the word "Bethlehem" in white lettering. The Bethlehem Steel company of Pennsylvania provided the support beams. This work was part of President Harry S. Truman's large-scale 1948-1952 renovation of the White House.
