In addition to ephemera, Brundage illustrated children's classics such as the novels of Louisa May Alcott, Johanna Spyri, and Robert Louis Stevenson, and traditional literary collections such as The Arabian Nights and the stories of King Arthur and Robin Hood.

She illustrated books and ephemera such as paper dolls, postcards, valentines, prints, trade cards, and calendars.

Brundage produced works for Raphael Tuck & Sons with an emphasis on attractive and endearing Victorian children.

At the same time she was also published by Wolff Hagelberg, Berlin, in near equal amount, except no book illustration and quite different subject and style.

Those postcards and the Tuck and the Hagelberg lines of fancy diecut valentines made Brundage the largest presence in U.S. art paper 1899-1910.

While "stereotypical" in form, they were not negative and might be compared to her "comical" treatment of romance with Tuck diecut valentine and postcard images where the intent is not ridicule but rather positive dramatization.
