You can find Idun and Isak in all departments in the Buskerud museums, perhaps they have hidden in an exhibition, or they inspire you in an activity booklet, a quiz or something as simple as coloring them. They change their clothes according to which department in the Buskerud Museums they belong to.
Idun and Isak at Lauvlia are wearing clothes that Inga (Th. Kittelsen's wife) and Theodor Kittelsen used. Inga in her evening dress, which you can see inside the artist's home, and Theodor with a sketchpad, brush and straw hat.
Idun and Isak are designed by Martine Solstad Larsen, Historical Art & Crafts
