UNITED KINGDOM - AUGUST 07:  A young boy and girl, both in school uniform, hold hands as they walk by. This photograph, taken for Photographic Advertising Limited, was sold to companies in New Zealand and South Africa. In England it was used by the London Conservative Union and ICI Limited. Images of children are common in the Photographic Advertising archive. Photographs of bright, smiling boys and girls were used by advertisers to promote a wide range of products. 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.
