Big Mac Turns 40

The world's largest Big Mac sculpture (14 feet high, 12 feet wide), at the grand opening of the McDonald's Big Mac Museum Restaurant in North Huntingdon, Pa., Wednesday, Aug. 22, 2007.

The restaurant opened in honor of the 40th anniversary of the Big Mac.

Normally, a 40-year-old sandwich would be something to be avoided.
Unless you're one of millions who flock to McDonald's each year to chow down on a Big Mac. The triple-decker burger, which helped breed America's super-size culture and restaurants' ever-expanding jumbo meals, is turning 40.
The Big Mac was first introduced in 1967 by Jim Delligatti, a McDonald's franchise owner in Uniontown, Pa. A year later, it became a staple of McDonald's menus nationwide.
