Howard Chandler Christy’s painting of the signing of the United States Constitution was commissioned in 1939 as part of the congressional observance of the Constitution’s sesquicentennial. Completed in 1940, the 20-by-30-foot framed oil-on-canvas scene is among the best known images in the United States Capitol. It is on display in the east grand stairway of the House wing.
