Last week we highlighted celebrities that looked like sports logos. Today, we take on advertising's biggest icons and their celebrity look-a-likes. We don't care if you call them pitchmen, spokesmen, brand icons, brand logos or brand mascots, 'cause we've scoured the pages of Advertising Age, ADWEEK, BrandWeek, PRWEEK, and consulted with our nation's top advertising gurus to determine our nation's most successful "product pitchmen." Once you get a glimpse at the real faces behind these brands, Big Macs and Whoppers will never taste the same.
