Who writes the stories of Tex?
Almost exclusively at the beginning of the series G.L. Bonelli. In 1976, he allowed his son Sergio to take over (without, however, allowing him to sign the stories). Bonellis real successor was Claudio Nizzi, who took over the series in 1983. Of other authors responsible for this series, the only one still around is Boselli. Look at the Index of the Writers.
