The 'Face from Space' took more than 3,000 hours to create from inception to launch and was built by Synergy, a leading event company.

From the KFC news release ( Which can be found at: http://www.kfc.com/about/pressreleases/111406.asp ):

The logo consists of 65,000 one-foot by one-foot painted tile pieces that were assembled like a giant jigsaw puzzle: 6,000 red, 14,000 white, 12,000 eggshell, 5,000 beige and 28,000 black.

The logo took 24 days, working around-the-clock, to manufacture and ultimately produce. It then took six days on site to construct the logo, during which time the logo design pieces were kept hidden and under cover from identified and unidentified flying objects.
