Renowned Scottish artists - including Peter Howson and Jack Vettriano - have donated works for auction to help raise funds for a mum-of-three battling "incurable" cancer.

Artworks up for grabs at the charity event include a signed print of Billy Connolly, donated by artist Rachel Maclean, which was originally unveiled as part of Glasgow's City Centre Mural Trail in celebration of The Big Yin's 75th birthday this year.

Playwright and artist John Byrne has donated a limited edition print by John Bellany from his own collection, while a signed first edition copy of Alasdair Gray's novel Lanark is also on offer.

All funds raised on the night will be donated to Claire Bothwell, 40, who has been diagnosed with "incurable" bowel cancer and lymphoma.

Ms Bothwell, from Glasgow, hopes to raise £100,000 to fund pioneering treatment in America or Europe.

Family and friends launched a mammoth fundraising campaign in response to her diagnosis and have collected over £74,000 so far.

The fine art auction will take place at the Centre for Contemporary Arts (CCA) in Glasgow on Thursday from 7pm.

Mum-of-three Claire Bothwell is calling for everyone under the age of 50 and the medical profession to be more aware of the symptoms of bowel cancer.

Ms Bothwell told STV News: "If I'd been over 50, I would have been seen and diagnosed within two weeks and that wait has really affected my prognosis and I'm now looking at having incurable cancer and a limited lifespan.

"It's devastating, you know, but you just have to pick yourself up and look for hope anywhere you can find it."
