Frankie Howerd, this truly great actor and comedian toured his own Variety productions upon the theatre stages during the 1950s period. He obviously liked circus art and performers because he booked into the shows the Sandow family acts. This playbill is for the Empire theatre Leeds for 1955 but I do remember almost the same playbill for Portsmouth in 1956. (Sincere gratitude to whirligig-tv.co.uk)
Some more great playbills with one showing Richard Hearne with Max Bygraves at the London Palladium. Sir Bruce Forsyth lower down the poster from Frankie Vaughan. See the thread; The Sandow Family Circus Variety History and the period 1966 where I represented Richard Hearne.
