A full set of street artist Stik’s iconic ‘Sleeping Baby’ print, which was adopted as the mascot of the hospital’s junior doctors strike, is due to come under the hammer at the prestigious auction house Christie’s on Thursday.

The prints, expected to sell for £2,000 to £3,000 as a set of four in red, blue, yellow and gray, will raise money for the Homerton University Hospital NHS Foundation Trust’s Art Charitable Fund.

Stik already raised £50,000 for the hospital by selling 500 silk screen prints of the sleeping baby which replicates a mural he painted there.

Stik, who has painted his distinctive stick-figure characters across the globe from New York to Tokyo, spent years living on the streets before he found fame, where he came under attack from thugs on more than one occasion.

He wanted to do something to “give back” to the NHS hospital which he credits with saving his life on more than one occasion.
