A Cyrillic version of Quicksilver in use for Дикий волк (“Wild Wolf”), a science fiction anthology edited by V. Kovalev and published in the Научная фантастика (Nauchnaya fantastika, i.e. Science Fiction) series by the Узбекистон (Uzbekistan) imprint in 1992. It includes two novels by Gordon R. Dickson, Wolfling (1969) andThe Genetic General (1960), plus The Last Starship from Earth by John Boyd. The cover art as well as the interior illustrations are credited to V. Liss. This info was compiled by sergtj (bibliographic details) and NikolaSu (images) for Fantlab.ru.
Quicksilver was designed by Dean Morris and issued by Letraset in 1976. The original version didn’t include Cyrillic characters, and I’m not aware of a digital adaptation to do so.
