"Olivier Tallec's interactive, pencil-case-shaped picturebook Who Was That? hones memory and observation by asking children what they saw before the page was turned. It offers silly pictures of impassive kids and creatures (underpants on heads, bottoms in the air), and the chance to do better than adults. And once children have it by heart, you can invent new questions of your own." Sunday Times Culture
