Please note that our auction and prize draw are now closed.

This month, our founder Quentin Blake celebrates his 90th birthday. In celebration, Bonhams are hosting an online auction of his latest drawings. Bidding opens today and closes on 16 December. All the proceeds will go towards the creation of the national centre for illustration in Clerkenwell, London.

At (nearly!) 90, Quentin still spends every day in his home studio, drawing fantasy landscapes and characters brimming with personality. The auction includes 140 pieces, all in Quentin's signature freeform linework and watercolour, and made in the last year.

The auction includes one mystery artwork titled A Chance Encounter... This special colour illustration will be given to the lucky winner of our December prize draw. You can enter by Monday 19 December to win and share a personalised birthday message with Quentin.

You can see some of our favourites from the auction here, and the full collection online at Bonhams.
