This episode was originally written for French publisher Editiones Lug, who hired artist Antonio and Vincenzo Chiomenti to draw the episode. In France episode was published on Speciale Kiwi 19 (20.6.1964), interestingly in Italy it was published few months before (September 1963).
Another curiosity is that strip on Collana Lampo Zagor Seconda Serie N. 23 page 58 was omitted from Zagor Zenith 12.
