Walker Books is an independent British publisher of children's books, founded in 1978 by Sebastian Walker, Amelia Edwards, and Wendy Boase. The company published 18 books in 1980 and now publishes 300 books per year. In 1991, the success of Walker Books' Where's Wally? series enabled the company to expand into the American market, starting a sister company called Candlewick Press in 1991. In 1993, Walker Books also entered the Australian market by establishing another sister company, called Walker Books Australia. The company's logo of a bear holding a candle was designed by Helen Oxenbury.
