Zoë Wanamaker a.k.a Lady Cassandra has submitted an original piece of artwork to the Heart Research UK Anonymous heART Project.
Her piece is up for auction on eBay from now until the 13th October to raise money to take on heart disease.
Available here: https://www.ebay.co.uk/usr/heartresearchuk_shop
We've sent out hundreds of our A5 postcards to artists, celebrities, high profile names and our creative supporters, and we've had some fantastic artwork back.
The twist? Though the list of artists was available to all bidders, the artist of each individual piece is kept anonymous. You won't know whose artwork you've bought until it's delivered.
Let the guessing games begin ... can you guess which is Zoë's? See the image for a clue ...
Everything raised in the auction will be invested in pioneering medical heart research, making hearts healthier in local communities, masterclassses for clinicians and driving innovative education in schools.
