Here are 2 unfolded invitation cards to the groundbreaking ceremony of the McDonald's Swim Stadium(later renamed Uytengsu Aquatics Center). Event took place on December 30, 1981 at the University of Southern California. The stadium was built for the swimming and diving events for the 1984 Summer Olympics in Los Angeles. The artwork rendering of the stadium was done by artist Dan Nicholl. The cards have never been folded and unfolded they measure 8.5" by 6.25". It's nice to have 2 for framing purposes. Made on nice textured paperstock. Great shape. 5.00 shipping.
