The Box was first published in Belgium and Holland by Clavis Uitgeverij, Hasselt- Amsterdam in 2012; translated into English from the Dutch by Clavis Publishing (no translator listed), New York, 2012.
Wild-haired Kobe becomes Kenny in translation. What was most striking to me about The Box is the rather unusual media, which are photographs of clay and cloth figures, created digitally with Photoshop. They are very distinctive, with expressive faces and gestures that I think children will appreciate.
