Listen and touch book 2: Who’s the tallest?: a tactile story book for slightly more advanced users of tactile graphics and an entertaining introduction to the concepts of ‘tall’, ‘taller’ and ‘the tallest’, as the child joins Whispur the cat, Curley the poodle and Cheeky the mouse, trying to find out how tall they are. A cassette included with the book makes the story even more enjoyable.
