Completion of Mount Rushmore

Date: October 31, 1941 • Location: Custer, United States

Approximately 400 workers completed the 60-foot (18 m) busts of U.S. presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln at Mount Rushmore in South Dakota.

A bust is a sculpted or cast representation of the upper part of the human body, depicting a person's head and neck, and a variable portion of the chest and shoulders. The piece is normally supported by a plinth. The bust is generally a portrait intended to record the appearance of an individual, but may sometimes represent a type. They may be of any medium used for sculpture, such as marble, bronze, terracotta, plaster, wax or wood.
