SHELBYVILLE, Ky. — KFC founder Colonel Sanders’ signature black bow tie, original cash register and dozens of other personal items sold Tuesday night in a public auction, while his former home and another restaurant he owned were up for auction later in the week. “Colonel Sanders was the original celebrity chef,” said Bill Menish, whose firm, The Menish Group, is conducting the auction. A clip-on black ribbon bow tie worn by Sanders, which he is depicted wearing in the KFC logo, sold early in the night for $8,000. “He didn’t dress like that before he was starting to build Kentucky Fried Chicken,” Menish said. Sanders sold KFC in 1964 to a group of investors, but continued as a brand ambassador for the company.
