The article is concerned with the map-iconotexts of the Moomin-books by Tove Jansson. A methodology is developed, focusing To begin with the focus is on the verbal, pictorial and cartographic elements, and the ways in which these aspects interact and overlap in these books. In a second move, tThe maps are then analyzed with regard to their functions: being part of the plot, helping the reader keep track of plot and setting, and stimulating the reader’s imagination to produce an imaginative space. It is shown that the Moomin maps are rich and complex texts with a great deal of overlap, formally and functionally. It can also be conceded that the Moomin maps invite the reader to engage imaginatively with Moominworld, to play Moomintroll’s “serious game” of map reading. Finally, it is hoped that the two-step methodology worked out in the article can be fruitfully applied more generally on maps in children’s literature.
