Wordless picture books such as Gabriel Vincent's ``Enjour'' and Shaun Tan's ``Arrival'' (Wordless Picturebooks) I am researching picture book expressions, focusing on narrative expressions.Pictures are a medium that can convey a variety of information in a way different from text, and I am focusing on expression and thinking about what kind of ideas can be used to convey a story using pictures alone.I am mainly interested in the image expression of printed materials for the general public, including manga and illustrations.
