Jean Adamson was a British writer and illustrator of children's books. She was best known for the Topsy and Tim books, the first of which was published in 1960 and which have sold 27 million copies. Adamson's creations were also featured widely on television in 84 episodes of Topsy and Tim.
Exactly as it says in the title "Topsy and Tim Go To The Park". Some good advice about not running in front of swings. A solid book but not very exciting.
