Manchester Grammar School pupils visited the Christie Hospital to view artwork they produced in memory of former student Robert Broude, who was a patient in its teenage cancer unit.
Robert died, aged 19, from a rare form of cancer in 2004. His family and friends have raised more than £250,000 for the hospital, funding "Rob's day unit", a spacious area for patients treated on a day care basis.
His parents Peter and Helena and grandmother Sandra joined the viewing group, Helena Broude saying: "The paintings look fantastic. The pupils have incorporated some of Robert's favourite things such as Liverpool Football Club. I know Robert would be impressed."
Inspired by the work of Andy Warhol, the art has a north-west theme with celebrity images including Gary Barlow, Amir Khan, Tony Wilson and the Gallagher brothers.
