One day they knock on the door of the beginners' class at Gustaf Vasa school, near Vasaparken, where they live under a big fir tree. They each get a small, small bench and they become best friends with the boy Gunnar.When he greets them in the park, they show off their skating skills.The story of Peter and Petra from Nils Karlsson-Pyssling is here published as a picture book with illustrations by Kristina Digman.
