This color photograph by Jack E. Boucher was taken from inside the White House through the window above the north entrance. The fountain on the North Lawn and Lafayette Square can both be seen through the North Portico columns. Boucher served as chief photographer for the National Park Service's Historic American Buildings Survey. He spent four decades documenting hundreds of historic buildings, including the White House.

This is a photograph of the North Front of the White House with a partially stripped facade. Following a two year study of the White House's sandstone walls and white paint, the National Park Service commenced a project to restore the exterior in 1980. Over the years, more than 30 layers of paint were added to the exterior walls, becoming so thick that additional paint had difficulty adhering and obstructed the original carved stonework. The restoration of the walls took place over 15 years and was completed in 1996. This photograph captures the stripped walls and scaffolding from the project.

This photograph of the northeast gate of the White House was taken by Jack E. Boucher for the Historic American Buildings Survey (HABS) in 1992. The northeast gate of the White House opens onto Pennsylvania Avenue.

This photograph of a milk trough was taken by Jack E. Boucher in 1976 for the Historic American Buildings Survey (HABS). The milk trough was carved for Andrew Jackson in 1834 by Robert Brown, one of the original Scottish stonemasons to build the White House in the 1790s. The trough was later used as a garden ornament.

This photograph taken by Jack E. Boucher shows the South Portico of the White House protectively wrapped as 40 layers of paint are removed. The paint had become so thick as to obscure the craftsmanship of the original stone carvers. The entrance to the house remains open for continued use.

This photograph captures bankers-marks found engraved on the sandstones of the White House walls. Bankers-marks were a stonemason tradition with origins in Scotland and England. The first stonemason hired for White House construction, Collen Williamson, was a Scot who likely continued to enforce this tradition while working on the Executive Mansion. Historically, the marks represented apprentices upon the completion of their training and were derived from the marks of their teachers. The marks also indicated that a stonemasons' work was paid for by "measurement," not wages. The marks on the White House stones were uncovered during President Harry S. Truman's renovation of the Executive Mansion from 1948-1952. President Truman gave a number of the stones to Masonic Lodges across the country while some remained in the White House. Several of these marks were displayed in two reconstructed fireplaces on the Ground Floor.

This is a photograph of the North Front of the White House during the Ronald Reagan administration. In this photograph, layers of paint have been stripped off of the White House in preparation for a new coat of paint. Scaffolding covered the left side of the North Front so painters could work on the restoration.
