Secret Agent Underground Submarine Fortress Painted Backdrop BD-0355
Depicts a submarine moored in an underground channel with stairs rising to other huge subterranean structures, where two men with guns stand overseeing the enormous cavern. Giant pipes wind their way up the rough hewn stone walls among protruding boulders, while in the foreground we see our hero Secret Agent brandishing a gun, hidden behind a wall, waiting for his opportunity - nearby ominous metal drums are marked with radioactive symbols.
