Opening in 1910 (Walker 1995, p. 80) it would show the very best of films such as The Test of Honor starring Mr John Barrymore (Semaphore Wondergraph, The Advertiser(Adelaide), 1 November, 1919, p. 12). In September 1920 Daniel Clifford purchased the suburban circuit of Wondergraph, which included the Semaphore Wondergraph for a sum of £15,000(Thiele & Lang 1991, p. 52) and a more permanent structure would be built on Semaphore Road.
