Sheffield artist Pete McKee is urging members of the public to become a life-saver and sign up to become an organ donor after he underwent a liver transplant.
The 51-year-old had the operation in Leeds a few weeks ago and is now recovering at home in Sheffield.
McKee, who has a shop and gallery on Sharrow Vale Road, said his diagnosis was caused by a rare genetic condition and sparked a 'massive change' in his lifestyle and perspective, including giving up drinking and a number of diet changes.
Posting through his official Instagram social media account he urged people to sign up to the donor register - as they could save someone's life.
He said: "Obviously I'm not out of the woods yet and the road is very long and winding. But at least I'm on that road and not parked in the lay-by.
"Thanks to everyone of you for your messages of love and support and the hospital staff for giving me the energy to go forward.
"Please sign up to the donor list it only takes a moment and could make a huge difference: https://www.organdonation.nhs.uk/faq/organ-donor-register/."
He also posted a written note to the account which read: 'I came home, held my wife in my arms and cried my eyes out' which prompted messages of support from several fellow Instagram users and received more than 2000 likes.
McKee, a cartoonist for the Sheffield Telegraph's sports section, has been responsible for a number of popular larger than life street art projects including 'The Snog' on Broad Lane.
Football features heavily in the artist's work but he has also worked with Oasis guitarist Noel Gallagher and fashion designer Sir Paul Smith.
