"Titan of industry" and Las Vegas founder William A. Clark was an insanely rich man who spent a good amount of his fortune on expensive and impressive art and other rare things. Clark died back in 1925 and left all of his worldly possessions to his family. Christie's is hosting an auction of the Clark Family Treasures on June 18 with furniture, paintings, rare books, instruments, tapestries, and other pieces.

Life+Times got an inside look at pieces from the auction and produced the "Off the Wall" video segment above. To learn more about the auction, head over to the Christie's page.
