As part of the grand opening of the VI CIOFF®️ World Folkloriada, a special ceremony of cancellation of a post-marked envelope with the festival's logo was held at the "Ufa-Arena" Ice Palace. The event was attended by the President of the International Council of Folklore Festivals and Folk Arts Organizations (CIOFF) Philip Beaussant, the Head of the Republic of Bashkortostan Radiy Khabirov, the Chairman of the Federation Council Committee on Science, Education, and Culture Lilia Gumerova. In honor of the VI CIOFF®️ World Folkloriada, a special stamp with the festival's logo was issued to the postal circulation. A similar emblem and the inscription "VI CIOFF®️ World Folkloriada  Ufa, July 3-10, 2021" is contained on a postal envelope, also issued the day before. The first impressions of the stamp on the envelopes were put down by Philip Bossan, Radiy Khabirov, and Lilia Gumerova. All participants of the event had the opportunity to send a festive envelope with a unique stamp to any place in the world directly from the Ufa Arena, where the mobile stand of the Russian Post was located. It is noteworthy that it will be possible to cancel postal products with a special postmark of the VI CIOFF®️ World Folkloriada only during its holding - from July 3 to July 10. The issue of such stamps with fixed dates does not happen often, so such an event always attracts attention, especially of philatelists. Stamps, envelopes, and postcards with such an imprint immediately acquire a special value among collectors. The postal envelopes with the emblem of the VI CIOFF®️ World Folkloriada have been issued in a 500-thousandth edition and have already been received by the offices of the Russian Post.
