The Sleeping Baby mural by street artist superstar Stik was adopted by junior doctors in their protest against NHS reforms, and now is being auctioned to raise money for Homerton Hospital.
Four artist's proofs of the image, which Stik says represents the vulnerability of the NHS, will be sold at Christie's on Thursday (19 May).
Last year a sale of 100 screenprints of the mural, painted on the outside of the hospital, raised £50,000 for the hospital's neurological rehabilitation unit.

Stik is one of the world's most recognisable street artists. Formerly homeless, his trademark stick figures have appeared on buildings across London.
You can see the images at Christie's, 85 Old Brompton Road, SW7 3LD, from 9am-5pm today and tomorrow. The auction is on 19 May.
