This article is a qualitative and descriptive study, based on teaching students, aged 13-14, about epistolary art in France. First of all, the section based on a comparative reading of Calamity Jane’s Lettres à sa fille (1997 and 2007) and the comic book Calamity Jane (1967) by Morris & Goscinny is presented and some observations about presenting them in the classroom are detailed. Secondly, the article makes further suggestions to enrich these letters’ study, mainly by means of enunciative variations, life-narratives dealing with fiction and truth, but also the narrative and graphical integration of actual photographs pertaining to the historical character. What makes these improvements possible is the new augmented edition’ of the letters in 2007, in which the question of an apocryphal manuscript is revealed to French readers, and also several graphic novels’ publication, since 2004, based on the first or the new edition such as Fontaine’s Calamity and Blanchin & Perrissin’s Martha Jane Cannary. These comic books allow us to study with students Calamity Jane’s modern myth reception’ in Francophone countries in Francophone countries.
