* JOHN BYRNE RSA, BILLY CONNOLLY (75th Birthday) artist's proof giclee print, signed boldly in pencil 50cm x 40cm Mounted, framed and under glass Note: A limited edition of 150 (unsigned) giclee prints have been published for Glasgow Museums to commemorate the comedian's 75th birthday. John Byrne was one of three artists (with Jack Vettriano and Rachel Maclean) commissioned by BBC Scotland and Glasgow City Council's mural team to produce a specially created portrait to be transferred in giant size to walls across Glasgow city centre. Byrne's depiction is located on Osborne Street. The unique hand signed print offered was gifted to the vendor by John Byrne to be auctioned to raise funds for Cancer Research UK and the hammer price will be paid in full to the charity without deduction. The story of the artworks was told in the programme ''Billy Connolly: Portrait of a Lifetime'' screened recently on BBC One Scotland.
