Zagor portachiavi
The Zagor key ring was sent as a gift by SBE, then Daim Press, to those who responded to the referendum held in 1981. It was a real questionnaire to answer: six questions including which was the best story, which was the worst, one on supporting characters in adventures, friends or enemies, one on genders of the new series that the publishing house should have produce, one on the presence or absence of advertising.
To whom sent the answers, this was sent free of charge key ring, as was also done for Tex and Mister No. That of Zagor has the characteristic of being probably the most difficult gadget to find on the market due to the fact that, being enamelled in blue, it could very easily deteriorate. Even more difficult is finding it in its original plastic bag as it was sent to home.
