The images were small gifts Killip made to individuals in Askam.
Mr Northcott’s friend Lee was photographed by Killip in Boy with Pigeon and given back the print, which features in the exhibition.
“These images offer us an important and poetic record of a community shaped by industry, landscape, and resilience,” Mr Northcott said.
“While selected works in the series have been shown internationally, the complete series has never been shown in its entirety since Chris Killip shared his work with the Askam community soon after he’d made it, in 1982.”
The exhibition features 20 photographs from 1982, hand-printed by Killip and loaned by the Chris Killip Photography Trust and Martin Parr Foundation, and 59 digital scans which include those from within the community.
