Don Winslow of the Navy #51

Don Winslow of the Navy #51 delivers a tense dungeon standoff straight from Fawcett's November 1947 lineup. The cover shows Don chained to a stone wall, straining against his shackles while the masked, pirate-hatted Singapore Sal stands coolly at his side — arms folded, clearly in control — with the cover itself warning that she "points the way to disaster." It's a wonderfully atmospheric setup, rendered with sharp linework by artist John Jordan and inker Carl Pfeufer that makes the danger feel immediate and the villainess utterly compelling.
