Sir Quentin Blake's work is loved by generations of children who grew up reading Roald Dahl, and from March some specially commissioned portraits will be on display at the Millennium Library.

Painted in watercolour to mark the centenary of Roald Dahl's birth in 2016, Sir Quentin created 10 portraits of some of Dahl's best loved characters as though they had posed for him.

From March to June the works will be on display at the Millennium Library after the team there won a bid to bring the exhibition to Norfolk.

The works have already been displayed in Hull from July to September last year, and will be heading to Wakefield after coming to Norwich.

Describing his project Sir Quentin said: 'The Roald Dahl Centenary Portraits ask you to imagine that a number of Dahl's characters have been invited to come and sit for their portrait; they are depicted, not quite as they appear in the illustrations, but more formally.

'The perceptive spectator may notice that one celebrated couple declined to appear together, and another formidable personality obviously disapproved of the whole venture. Nevertheless, I hope visitors will be happy to see this group of well-known characters treated as though they were real people – which, of course, to many of us they are.'

Kath Griffiths, locality manager at the Millennium Library, said: 'The idea is the character has been invited to sit for their portraits rather than taking scenarios from the books, so he is doing it in a slightly different context really.

'It will open to the public on March 7 and will be with us until early June.

'The Millennium Library and British Library are part of the Living Knowledge Network, and it is through membership of that we were able to pitch to have the exhibition come to Norfolk.

'We were one of the successful libraries to pitch for it. I think Quentin Blake is a much loved illustrator and Roald Dahl books really capture everybody's imagination.

'People grew up with Quentin Blake's illustrations so he is such an inspirational person. We are so proud and excited to be able to bring this amazing collection to Norfolk and be able to share them with the public.'
