This commemorative stamp from Hungary was issued in 1967 to mark the International Stamp Exhibition (Nemzetközi Bélyegkiállítás) held in Budapest. The design combines a philatelic exhibition emblem with a beautifully illustrated Small Tortoiseshell butterfly (Vanessa urticae) resting on a plant. Printed in vibrant colors, the stamp highlights Hungary’s artistic stamp design tradition of the 1960s. The denomination of 2.60 Forint is prominently displayed, and the left panel features the exhibition building motif. Collectors appreciate this issue for its blend of philately and natural history themes, making it attractive for both butterfly and exhibition topical collections.
