Sadly, Giulio Chierchini passed away at the age of 91 yesterday: www.afnews.info/wordpress/2019/08/18/giulio-chierchini-passed-away/ Even though his stories aren't liked by everybody (especially the two-row airbrush stories with Bubble Billy I think was his name, innit?), he is an absolute legend that deserves to be remembered!

It's interesting to note that other artists at the time also adopted the format (two-tiered pages with painted backgrounds) for a while, such as Giuseppe Dalla Santa, Marco Ghiglione or Sergio Asteriti. Not forgetting Moreno Chisté who was also involved in the colouring of this amazing looking story:
