Since the first edition of the Renata Tebaldi International Voice Competition in 2005, the San Marino Philatelic and Numismatic State Society has issued special POSTMARKS dedicated to the event on the final evenings.
Indeed, such postmarks were used only on the days of their issue corresponding to the dates when the final concerts of the various editions took place.
The originality and the reduced number of postmarks make them a little big treasure, which besides being a source of pleasant curiosity for the audience, interest several collectors worldwide, who will succeed in getting such unique pieces.
The Renata Tebaldi Foundation is the only institution which has and owns such postmarks.
