Shot at the singer's London flat, the three images of the former Pink Floyd frontman were taken by music photographer Mick Rock.

Capturing Barrett after the onset of his mental illness, the auction is likely to include portraits from Rock's photoshoot for Barrett's 1970 solo album 'The Madcap Laughs'.

The photos will go up for auction at Phillips de Pury in London on November 21.
