'This title [uses] a humorous approach to nonfiction as it looks at what makes a wall a wall . . . Unusual, informative, and fun, the book will be an easy book talk for the librarian and an easy book report for a reluctant reader.' Booklist
'A lighthearted but searching and intelligent exploration of the concept and lore of walls, from dry-stone structures to honeycombs and tin cans. Succinctly phrased in sprightly verse, supplemented with labels and remarks of the appealing Humpty-Dumpty-like figures that people Baron's carefully limned settings . . . [t]he idea is developed with imagination and in surprising depth . . . excellent nonfiction, sure to amuse.' Kirkus Reviews
'A light-headed but informative book... This is a fantastic book that covers all aspects of walls, from science to geography. It is written in rhyme and has detailed amusing cartoon pictures which children can explore again and again. An excellent non-fiction book that will make you want to know more.' mumsense
