PEORIA, Ill. -- A die-hard Chicago Cubs fan has found a 2011 World Series championship cap autographed by rival St. Louis Cardinals players -- and he wants to give it back.

Joe Couri tells the Journal Star in Peoria he was driving along Interstate 74 in central Illinois when traffic backed up because of an accident. He says he saw the hat among debris on an off-ramp.

The 38-year-old from Brimfield says the hat appears to be signed by David Freese, Yadier Molina, Jason Motte and other players.

Couri wants to return the hat to its owner despite the heated rivalry between the two teams. He says whoever comes forward will have to know about an unexpected signature on the hat or "have a picture of himself wearing it."
