Yes, "Л. Януш"="L. Yanush" is easily recognizable but I did not find this artist by search in Russian because in Russian Януш is a very common Polish name (= Janusz) and internet is full of this name. It is funny how one can take something very common, transliterate it from latin to cyrillic and back (Janusz -> Януш -> Yanush) and obtain something rare!
