Whose tail is that?' is part of a beautiful series of toddler books by Joukje Akveld. In each part the question is always asked: who or what belongs to this? The illustrations in this part are by Martijn van der Linden. On the left a tail, on the right four animals: a giraffe, a penguin, a crocodile and an elephant. Whose tail is that? Once the choice has been made, a beautiful drawing with the answer follows. There are some nice jokes in there: how about a crocodile with a floral backpack, or a ring-tailed lemur with a selfie stick? This toddler series is illustrated by the best illustrators in our country. Each part by someone else, who always manages to give it a surprising twist. The illustrations in this part were made by award-winning illustrator Martijn van der Linden, who conjures up the most beautiful animals.
