Collecting and cataloging objects (stamps, cars, films, figurines, and of course comics) is basically a way of giving meaning to life. Therefore it’s not unusual for the search for a missing piece to become the primary purpose in the existence of a collector. And upon reaching the goal, it’s likely, maybe even certain, that the collector will immediately create a new one, because the search for a rare item is so exciting (especially when it is something that is also coveted by others); the experience of finding it and making it your own is so rewarding. But the activity of collecting cannot be reduced simply to the pure private pleasure of possession and contemplation of these objects: it actually has a huge social significance in the public domain. It is only thanks to the work of gathering and collecting pursued by so many collectors that humanity can access works and objects that are pieces of evidence in documenting past eras, and which, without the collectors, would have been irretrievably lost. Comic collecting has all these features but offers the additional pleasure of reading material that in fact in most cases is interesting and beautiful not only in terms of its content, but also in its presentation and design. This is the case of the 100 rarest pieces of comic collecting, among which feature characters and memorable events that in some cases have become part of the collective imagination. It ranges from Tex to Signor Bonaventura, from Mickey Mouse to Dylan Dog, from Corto Maltese to Diabolik. Real jewels of Italian creativity and publishing that may well succeed in impressing and convincing even those who are not yet passionate about collecting.
