Klyuchevskaya Volcanoes Appraisal

1965 USSR Postage Stamp - Klyuchevskaya Group of Volcanoes

This is a vertically oriented postage stamp issued by the Soviet Union (USSR) in 1965, part of a set featuring volcanoes of the Kamchatka Peninsula. The stamp is printed on paper with standard perforations on all four sides. The central illustration depicts a photorealistic mountain landscape of the Klyuchevskaya Sopka volcano group, featuring snow-capped peaks against a clear blue sky with green tundra in the foreground. The top of the stamp features the Cyrillic text 'ПОЧТА СССР' (Post of USSR) in black, with a red denomination of '4k' (kopeks) and the issue year '1965' printed vertically in red. Along the right edge, vertical Cyrillic text identifies the location as 'КЛЮЧЕВСКАЯ ГРУППА ВУЛКАНОВ'. Notably, the stamp is mounted on a black backing, likely a philatelic hinge or mount. A significant feature is the partial circular black postmark in the lower right corner, indicating this is a 'used' stamp. The postmark includes part of the city name 'МОСКВА' (Moscow). The condition appears good with intact perforations, though the presence of the cancellation mark is a primary condition factor for collectors. The color remains vibrant without visible fading, and the printing quality reflects the period's standard for Soviet commemorative philately.
