Started in 1975 by the same authors of Blueberry, Charlier and Giraud (Moebius). After Charlier death it has become a volume for children.
The three first issues were originally part of the Blueberry volume. Since issue #4, Colin Wilson was the penciller, and since issue #10, it is Michel Blanc-Dumont. Jean-Michel Chariler kept writting the plots until his death, in 1989. Since issue #7, Corteggiani is the writter.
Like the Blueberry volume, it spent a few years being published outside Dargaud (Novedi and Alpen).
Spanish translation of the series in La juventud de Blueberry.
