The lobby wall of 30 Rockefeller Plaza originally contained the controversial "Man at the Crossroads" mural by Diego Rivera. This was destroyed in 1934 and replaced with a mural by Josep Maria Sert titled "American Progress". "American Progress" depicts a vast allegorical scene of men constructing modern America and contains figures of Abraham Lincoln, Mahatma Gandhi, and Ralph Waldo Emerson. Sert's other murals, all located in the northern ground-floor corridor, include "Time"; "Spirit of Dance"; "Man's Triumph in Communication"; "Conquest of Disease"; "Abolition of Bondage"; "Fraternity of Men"; and "Contest-1940", depicting different aspects of the world and mankind. Frank Brangwyn complemented Sert's works with four murals on the southern corridor, all of which symbolize humans' relationship with spirituality.
