A photograph of a smiling woman typist answering the telephone, taken by Photographic Advertising Limited in 1949. This image was first used by 'Psychology Magazine', and was later used as an illustration in the programme for the Middlesex Hospital Ball. Photographic Advertising Limited was founded in 1926 by a group experienced in photojournalism and film. The company created multi-purpose stock images with the potential for selling a range of products. Whilst enjoying its greatest success during the 1930s, it continued in business until 1977.
