Fox (City) Manager Noble Arnold continued to maintain the Fox as Atlanta's first run movie house in the early 60's with the revitalization of the Moller organ in November 1963 (courtesy Joe Patten), and a restored Vertical sign and new orchestra level seating in 1964. This free institutional brochure from 1965 touts the improvements and includes photos of Bob Van Camp at the organ console.
The brochure was advertised in an ad in the April, 1965 issue of Atlanta Magazine.
Charles Walker told me of his shock when one day in 1964 he saw a crane removing the Fox vertical sign. He assumed that that was the end, but a month later the sign rehung, completely restored and relighted.
