From the archives: Keith Haring was here
Artist Keith Haring took the New York City subway system by storm in the 1980s, with his drawings appearing on the walls of hundreds of stations. His art is known for expressing concepts of death, sexuality and war. Charles Osgood takes a look at how Haring managed to get his works up, in this profile first broadcast on the "CBS Evening News" on October 20, 1982.
