Harald Wiberg (1908-86) is well-known for his fine pictures of animals and nature. The book by Astrid Lindgren which Harald Wiberg has illustrated is Christmas in the Stable (1961).
He has also illustrated the picture-book The Tomten, containing poems written by Viktor Rydberg and Karl-Erik Forslund’s picture-book about The Tomten and the Fox. The staff at Rabén & Sjögren liked the pictures so much that they wanted to export them. Astrid was then given the task of reworking these poems into prose, the text of which has since been translated into several languages and been sold in Germany and the USA, and other countries.
