Michael Castellon includes several photos of the logo, and a time-lapse video of the logo being constructed.
From the KFC press release:
The giant Colonel Sanders logo was built off The World's Only Extraterrestrial Highway in Rachel, Nevada, also known as the "UFO Capital of the World," and the epicenter of inter-galactic communication.
"If there are extraterrestrials in outer space, KFC wants to become their restaurant of choice. For now, we'll be very content satisfying the entire human population with our Finger Lickin' Good Chicken. Besides, who knows if extraterrestrials even have fingers? If we hear back from a life form in space today - whether NASA astronauts or a signal from some life form on Mars - we'll send up some Original Recipe Chicken," said Dedrick.
The massive logo, which was referred to as the "Face from Space" by the project team, is so large it dwarfs one of America's largest and most famous landmarks - Mt. Rushmore. The huge carved faces of Presidents Washington, Jefferson, Roosevelt and Lincoln would all fit easily in the "Face from Space." There would even be enough room left over for a fifth presidential face in the Colonel Sanders logo!
It took a team of nearly 50 designers, engineers, scientists (including astrophysicists), architects and other professionals working nearly three months to conceive, create and execute building the world's largest logo."
