Man Confronts Hulking Dark Entity in Cabin Interior, Early Sci-Fi Pen-and-Ink

What's striking here is the bold use of pure silhouette to render the monstrous antagonist — a surprisingly modern compositional choice for its era. A determined man in shirtsleeves braces himself against a doorframe, pistol raised, as an enormous dark humanoid figure looms from the right, its form rendered entirely in dense black ink. A porthole-style fixture on the wall hints at a ship's cabin setting, grounding this confrontation in an aquatic or nautical mystery.
