This is a postcard published in the Mason’s Alpha series showing Piccadilly Circus looking east towards Coventry Street with Shaftesbury Avenue on the left. It is 1955 and the first spin off film from the 1953 BBC Television series “The Quatermass Experiment” is playing at the London Pavilion. “The Quatermass Xperiment” was made by Hammer film productions and starred the American actor, Brian Donlevy as Professor Bernard Quatermass and Jack Warner as Inspector Lomax. Donlevy was cast as a sop to the American market where the film was known as “The Creeping Unknown” and the British title left out the “E” in Experiment to emphasise the “X” classification made by the Board of Film Censors. Hammer made two more “Quatermass” sequels, “Quatermass II” in 1957 and “Quatermass and the Pit” in 1967. The film ran at the London Pavilion from 1st September until 22nd September 1955. The advertisement on the Shaftesbury Avenue side of the London Pavilion shows a stylized Wheatsheaf and the letters “CWS” and the words “Symbol of Value”, this was an advertisement for the Co-operative Wholesale Society whose purpose was to source and manufacture food, furniture, clothing and household products for sale to other Co-operative Societies. It was founded in Manchester in 1863 with the Wheatsheaf logo and is known for its introduction of the eight-hour day as well as introducing convalescent homes for sick employees. The society is now known as the “Co-operative Group”.
