This series, number 417, was the third series undertaken by Wills and Hepworth in their familiar small Ladybird format. The books were all written by Muriel Levy and illustrated with beautiful and vivid full colour pictures by Kiddell-Monroe. Wills and Hepworth published them between 1941 and 1948.
There are two stories in the book. Wonk is a very cute koala and is Peter's best friend. Wonk, like most Koalas, is often thinking of sleep, or falling asleep. In 'Adventures in the Dark' Wonk suggests they visit the garden at night to try to cool down. Even Peter is 'greatly surprised at Wonk's sudden daring' and tries to dissuade him. However, the daring attitude doesn't last for long when the night time animals startle a frightened Wonk and he ends up 'completely alone'. In 'Strawberries and Cream' it is the wish for 'something nice and cooling' which determines that the pair need to work for some money. A gardener offers them a job picking strawberries with strict instructions NOT to eat any of them. However, in true Wonk and Peter (and Ladybird) style, they seem to land on their feet by having their cake (or strawberries) and eating it too!
Originally published in 1941, this is the seventh edition in Series 417 published in 1947. Yellow/cream boards form the cover with a picture of Wonk on the front.
The front and back covers and spine are in one piece, just detached from the rest of the book. The top third of the spine is missing. The covers have some stains and are tanned. Inside, the pages are bright and clean.
