The Big Mac has become an American icon over its 50-year run. In 2007, the Big Mac Museum Restaurant was established in North Huntingdon, Pennsylvania, to honor the juicy burger. Its Big Mac sculpture is 14 feet tall and 12 feet in diameter. And in 2016, McDonald's division in the United Kingdom auctioned off a 740-milliliter bottle of sauce used in the burger for roughly $95,000 on eBay. McDonald's sold 1.3 billion Big Macs last year, according to the chain.
