Original 1940 U.S. one sheet for Yukon Flight, directed by Ralph Staub and starring James Newill, Louise Stanley, and Warren Hull. Part of the long-running Renfrew of the Royal Mounted adventure series, the film blends crime, aviation, and northern action in classic Republic Pictures style. Linen backed for preservation, this scarce Mountie-themed poster showcases vivid artwork and pulp-era design typical of 1940s serial adventures. Highly collectible among aviation and classic action enthusiasts.
