Two stylish die-cut board books that introduce the concept of colours. These two colours concept books are part of Walker's new range of concept board books that combine graphic pictures with ingeniously simple novelty devices. In this case die-cut pages reveal that strawberries are red, oranges are orange, bananas are yellow and so on. Each page has more cut off it than the one before, so that the layered images finally form a delicious-looking fruit salad (Strawberries are Red). What Is Black and White? works in a similar way, with the pages revealing that the night is black, the snow is white, the cat is black, the milk is white, and so on. But this time, the black and white pages are turned to reveal...a zebra!
