Most Kauka covers adopted a house style, but the artist responsible for this one (whom one source tentatively identifies as Vlado Magdic) seems to have tried to imitate Franquin, recreating a scene straight out of Spirou et les héritiers (Spirou #4, “Spirou and the Heirs”). The book is a digest collecting three issues of the anthology magazine Lupo modern, where that same adventure ran in installments under the title “Pit und Pikkolo: Onkel Gustavs Testament”.
