In pictures: Quentin Blake's illustrations from 'The Witches' to wallpaper

As Quentin Blake receives his knighthood from the Queen today, we look back at some of his distinctive ink and watercolour illustrations.

From his well-known Roald Dahl front covers to wallpapers and solo prints, Blake's whimsical, easily recognisable style has made him the nation's most popular illustrator.

He achieves his style with a scratchy pen, "it is better if it is scratchy because if it is neat work nothing happens. If it's scratchy or textured it takes on another life," he says.
