Celebrating its 25th anniversary, the World of Coca-Cola is offering a special deal Sunday: two tickets at $25, a 20 percent savings (available only at the ticket window starting at 9 a.m. that day).

The attraction beside Centennial Park also opens an exhibit Friday in its Pop Culture gallery in observance of the 100th anniversary of the contoured Coke bottle. "Kiss the Past Hello" (through May 2016) shows international artists and designers re-imagining vintage Coca-Cola advertising for the future.

More of these images are on view in the High Museum of Art exhibit "The Coca-Cola Bottle: An American Icon at 100" (through Oct. 4). Guests to either World of Coca-Cola or the museum can receive $3 off admission to the other site Sunday through June 19 at their ticket windows only.

The World of Coca-Cola opened in 1990 at Underground Atlanta and moved to Pemberton Place, beside Centennial Park, in 2007. Coke said more than 23 million guests have visited the attraction, coming from more than 75 countries, all U.S. states and the District of Columbia every month.
