These evocative black and white pictures taken in 1954 by internationally-renowned photographer Marc Riboud capture a grimy, northern industrial city struggling to emerge from post-war austerity – a place of factories, washing lines strung across cobbled streets, back-to-back houses with outside toilets, corner shops and pubs serving Melbourne bitter.

After lying forgotten for 50 years, the captivating images were discovered in 2004 and next year up to 60 of them will go on display at a special temporary exhibition to be mounted at the new Leeds City Museum.

'A Lasting Moment' is due to open on January 10 and run until March 21. Officials at the museum are keen to trace people featured in the old black and white shots so that their storiescan form part of the exhibition

A selection of the photographs can be seen on the museum's website - wwwleeds.gov.uk/citymuseum. People who recognise anyone in the pictures is asked to contact the museum on 0113 214 1571 or email people.search @leeds.gov.uk.
