Kapitan Kloss

A Polish espionage series set during World War II, Kapitan Kloss follows the titular agent as he operates deep behind enemy lines. Published by Sport i Turystyka from 1971 to 1973, the 20-issue run was most frequently illustrated by Mieczysław Wiśniewski, whose clean, dynamic artwork defined the strip's look. The series stands as a classic of Cold War-era Polish comics, blending wartime adventure with the spy-thriller genre.
