The Landmark's interior designer was Las Vegas resident Leonard Edward England, who designed the ground floor to include a colorful and primitive Incan theme, which gradually changed to a Space Age theme on subsequent floors. The interior included $200,000 light fixtures, glowing, red-colored Incan masks, and a burnished metal wall sculpture representing a Cape Kennedy launch. The interior also included 65 tons of black and white polished marble, and carved mahogany woodwork from Mexico. In addition, the interior featured murals depicting the eight Wonders of the World, which included the Landmark tower.
