"This will be a nice addition," curator Steve Henry said. "In the future we are hoping to accumulate at least one costume from each of his new movies."
Clooney's uniform will be placed among his aunt's memorabilia. Henry said the new display at the Rosemary Clooney House Museum is scheduled to be unveiled June 7.
"We were at the premiere of 'Leatherheads' in March and were told the entire football costume, from the cleats and socks to the helmet we had originally asked for, was ours to have for the museum," Henry told The Ledger Independent of Maysville.
George Clooney is a Kentucky native. He stars alongside Renee Zellweger in "Leatherheads," a romantic comedy set in the world of 1920s professional football.
Henry, a former Kentucky lieutenant governor, and his wife, former Miss America Heather French Henry, bought and converted Rosemary Clooney's house into a museum after she died.
