Fenn's works reached a wide audience and popularized publications with illustrations, expanding the field for other artists.
As Sue Rainey wrote in her book Creating a World on Paper: Harry Fenn's Career in Art: "Fenn's dynamic and appealing compositions set a high standard.
They built pride in America's scenic landscapes and urban centers, informed a curious, increasingly cosmopolitan public about foreign lands, and fostered an appreciation of printed pictures as artworks accessible to a growing middle class" (p. 1).
