The collection consists primarily of Underwood's pen-and-ink designs for these articles, with manuscript captions and notes to the printer; and illustrations for children's stories which appeared in THE SUN, ca. 1905-1910, together with typescripts, proofs, and printed copies of the stories, several of which are by Underwood. The collection also includes correspondence relating to a projected series of costume designs for THE LADIES' HOME JOURNAL, a manuscript of a work on geography, and scrapbooks and clippings relating to these projects.
