A set of familiar faces smiling from a mural have greeted travelers taking the escalator up to the terminal upon their arrival in Atlanta at Hartsfield-Jackson International Airport for close to 15 years.

But eagle-eyed passengers may notice the image of children at the Centennial Olympic Park fountains no longer appears as they come up from the underground people-mover train to the domestic terminal.

The mural is now covered by an advertisement for Porsche, touting Atlanta as the home of Porsche Cars North America. Porsche recently relocated its North America headquarters to a site near Hartsfield-Jackson.

The Porsche ad is set to run through mid-June. After that, plans are for a new digital screen to be installed in place of the mural.

As for the original “Spirit of Atlanta” mural by Atlanta artist Deborah Whitehouse?

“We don’t know yet what’s going to happen to it,” said Reese McCranie, airport spokesman. “We are in discussions now of what should happen.”

Since the 70-foot wide mural was completed, children in the mural have become adults, but their young faces became some of the best-known meeter-greeters at the world’s busiest airport.
