The French edition of Runequest is gorgeous. Beginning with that striking color cover art by Hubert de Lartigue, and the evocative line art inside (Alain Gassner’s work caught my eye), a lot of love went into this box set.
I also have some photos of two other RQ accessory books from Oriflam.

Runequest: French Edition Box Set
1987 … Oriflam
Contains thick RQ RPG French rulebook, tables booklet (Aides de jeu), Glorantha map in French.

With the box (with the Hubert de Lartigue cover) and the single color map, this is the 1987 first printing. There has been a second printing with a hardcover, no box and a full color map.
