[2] Beginning in 1961, she studied painting for four years at Brooklyn Museum Art School with Reuben Tam and her work took on a more mature and deeper emotional quality.

[2] Her works, including full illustrations and a regular column of drawings, appeared in Woman's Day.

[2] That year,[5] she also joined the Charles E. Cooper studio with a collection of illustrators, including D'Andrea, Coby Whitmore, and Jon Whitcomb.

[6] As magazines relied increasingly on photography to fill their pages, it became difficult to remain competitive as an illustrator into the 1960s, but Fox was one of the artists, like Bernard Fuchs and Austin Briggs, to create their own new and unique style.

[10] Fox was described as "an elegant, quiet woman, highly imaginative, gifted in design and a standout artist in a field overbearingly populated by men" by journalist Don Stewart.

[2][4] The New School[5] and Smithsonian American Art Museum / National Portrait Gallery Library maintain an artist file of documents related to her career.
