Always one to deliver the unexpected, Gavin Turk's latest exhibition contains work made not by himself but rather by 35 prisoners across the UK who have pain-stakingly hand-stitched coloured letter squares that spell out Gavin Turk's name.

According to the Independent, the prisons who stitched Turk's artwork were part of a rehabilitation program that teaches needlecraft and they would spend an average of 20 hours a week doing embroidery in their cells for wages.

Turk said he was inspired by Italian artist Alighiero E Boetti who used craftspeople in Afghanistan to make his embroided works. "I'm trying to question our contemporary values about authenticity," Turk told the Independent.

Early on in his career, Turk was (now famously) denied his MA degree from the Royal College of Art - the first time that had ever happened - when his degree show presentation consisted of an empty white studio with a blue English Heritage plaque that read: Borough of Kensignton / Gavin Turk / Sculptor / Worked Here / 1989 - 1991."

Turk's exhibition featuring the prisoners' embroidery - Gavin & Turk - is on at Ben Brown Fine Arts, London W1 until 20 April.
