Denis, you are right about the Corto Maltese tour in small edition!
I used my knoledge of Venexia with a track of Corto very well illustrated itinerary.
This is a very interesting book to have a more real vision of the town avoiding the very common places that tourists love so much.
You will find many places in this Venexia strange guide that Hugo Pratt used as background for Corto.
Yes a true fan (mant years ago) as many of my age.
