Collective manifesto by the members of C.C.I. It is a collective film, the result of an operation devoid of any aesthetic purpose: to verify the existence of any harmony between a fairly large group (twelve people) of members of the independent Cooperative. Someone, who had the idea, turned 60 meters of Ektachrome according to the moods –or discontent – of the moment and gave them to others to see. The others reacted, each with their own piece. It was then thought to call the film “circular letter”. It was not so simple and so quick: the operation, which started in June of ’68, ended in March of ’69.
