This cd single cover of Sin Sin Sin by Robbie Williams has been hand signed by Robbie at an event in London, England many years ago. He signed beautifully with a black pen. A personal dedication is part of the autograph. The CD is not included. There is no COA or proof available but I personally guarantee for the authenticity as I am a collector for 30 years. All of my autographed items have been obtained in person unless stated otherwise. If you do have any questions or concerns please do not hesitate to contact me. Thank you for your interest.
