The stories that Arabia Moomin mug True to Its Origins is based on, are less joyful than most of her books. Tove Jansson wrote Moominvalley in November, after she had recently lost her mother. You can feel that the novel is more melancholic and it reflects the feelings of loss and sorrow.

Arabias Moomin mug Sleep Well has a similar design and these mugs tend to get easily mixed up.
