Chris Riddell is British illustrator and political cartoonist, known for his cartoons in The Observer, and for a series of children’s books he has illustrated, written or co-written, including The Edge Chronicles, Goth Girl, Muddle Earth, and his new colaboration with Neil Gaiman, The Sleeper and the Spindle (images above, top three). The latter title is not yet formally released in the U.S.; there is a review on The Guardian, with an image gallery.
His own website focuses on his cartoons, including “Illustrations to Unwritten Books”; the latter consisting mostly of terrible (i.e. wonderful) literary puns.
Don’t miss his absolutely wonderful sketchbook blog (yellow pages above), which is an extensive Tumblog with some of his most imaginative, off-the-cuff and delightfully loopy work, along with various sketches, and a sort of intermittent visual diary of his comings and goings, some of them sketched in a lined accounting ledger used as a sketchbook.
