The Delineator was a major women's magazine of the later nineteenth and early twentieth centuries. In its heyday it was one of the "big five" women's magazines, along with titles like The Ladies' Home Journal. The publication began as a collection of patterns for women's fashions, which accounts for its name; later it expanded into a general-purpose periodical. Separate from the work of Baum, The Delineator also printed freelance illustration work from the pen of John R. Neill.
