Business partners Alonzo Roberts and James Chandler have been giving haircuts at the Deluxe Barbershop for 50 and 39 years, respectively.   Original owners included James Dixon, Jr. and Bill Hardy, who operated a barbershop in the same location around the turn of the century.   In March of 1995, the current owners moved across the street to the northside of the square.   The newly constructed building will continue the one-hundred-year old tradition of a continuously operated barbershop in Hannibal Square.
