Coca Cola Co., often viewed as a symbol of modern American culture, said on Thursday thatit had acquired a lost 1931 painting commissioned by the famous U.S. artist Norman Rockwell.
The Barefoot Boy was one of six Rockwell oil paintings commissioned by the soft drinkgiant between 1928 and 1935. Copies of the painting appeared on nearly 2 million CocaCola calendars, on posters and in window displays.
The painting, which shows a grinning boy in a straw hat and suspenders holding a bottleof Coke and a sandwich, disappeared from public view shortly after it was produced. It wasrecently discovered in the hands of a retired Virginia executive.
Coca Cola, the world’s No. 1 soft drink company, did not disclose how much it paid forthe work, but did say its value was in line with other Rockwell pieces.
The Barefoot Boy, however, is believed to be worth a little bit more than $345,000 recentlypaid for The Dugout, a 1948 Rockwell oil painting.
“This is an exciting and important link to our heritage by the great artist Norman Rockwelland is a reminder of the Coca Cola’s deep connection over more than a century with the peoplewho enjoy our products,” said Coca Cola Chairman and Chief Executive Officer Douglas Daft.
Rockwell, once criticized by art critics as an over-commercial lightweight, gainedwidespread fame in the 1930s and 1940s for works that often focused on the slow ebb and flowof life in rural America. He died in 1978 at the age of 84. Coca Cola said it was possibleThe Barefoot Boy would be displayed at its World of Coke Museum in Atlanta. The companyhas previously acquired two of the six Rockwell originals it commissioned.
It said it was still searching for the three missing Rockwell originals.
