More than 50 Magnum photographers have trawled their archives to choose a ‘pivotal image from their career’. You now have a chance to own one of the resulting prints for $100.

The 6x6in Magnum Square Prints, which come signed by the photographer and printed on archival paper, are available to the public until 12 June.

On its website Magnum says: ‘The idea was to give photographers an opportunity to reflect on their careers and identify a single picture that represents a turning point in their lives as image makers.’

Magnum adds that the prints are ‘editioned by time’, rather than quantity, as they will not be made available outside the sale window.
