Anjan Sarkar’s preferred illustration style is “wonky and slightly misshapen,” which he realized around the time that he started drawing with his children (who are masters of the wonky line). His work is influenced by illustrators like David McKee, Jill McDonald, and Maurice Sendak, whose books he read as a little person. Anjan is also unhealthily obsessed with a few contemporary illustrators such as Benjamin Chaud, Sara Ogilvie, and Neal Layton. Since becoming a full-time illustrator, he’s created illustrations for children’s books, animation, and advertising. Anjan works from a little studio in his house in Sheffield, England, where he lives with his wife and two kids.
