Redd Foxx was very fan-friendly and was usually happy to sign autographs. He probably signed more autographs in Las Vegas than anywhere else. Before his ground-breaking role as Fred Sanford, he was a top Vegas act. After Sanford and Son, he continued playing Vegas up until his death in 1991.
He owned several homes and one of them was in Las Vegas. He lost that home to the IRS and some believe that the Ghost of John Elroy Sanford (Redd Foxx' real name) is haunting it.
A Redd Foxx signed photo is worth in the $50 - $75 range. Most collectors would prefer a signed photo of Foxx as Fred Sanford.
