“The Fog Man shows again Ungerer’s aim: to take children seriously. Tomi Ungerer brilliantly harvests the atmosphere of an overcast sea. A dark, strained sea, which is never too frightful thank to the presence of the two children characters” (Die Zeit).

"... wonderful pictures that are set up in a rural and peaceful scenery, delicious derawings of animals and ladscapes with a colour chart based on gray, brown, blueish green and some touches of red. Ungerer can express feelings and emotions from a goneby age, but that age looks familiar to us because is the age of marvelous tales, of stories about the beginning of things, about how important is to take the reins of your life". (Ana Garralón) .

"Acclaimed author Tomi Ungerer success in giving form to the fog, the moon above the sea, the tense atmosphere on just a few pages. Conceived as tribute to Ireland, this is a thrilling, fantastic book" (ABC Cultural).

“… What I find interesting in this wonderful tale is the symbolic meaning that it contains and that has left me completely dazzled (…) An absolutely wonderful story. Extraordinary” (Peb Bruno).
