[4] During her time at American University, Marrs was introduced to comic strip artist Tex Blaisdell by his daughter, with whom she attended school.

[3] At the same time, Marrs also worked for CBS News in Washington, DC, at WTOP, where she created artwork for the station and also drew live editorial cartoons on Saturday nights.

In the first issue of Wimmen's Comix (1972), Marrs' "All in a Day's Work" epitomizes how a woman's only leverage in a male-dominated society is to utilize her body to negotiate politics.

Her story, "My Deadly Darling Dyke," published in Gay Comix #3 (Dec. 1982) is a popular and outspoken interdisciplinary crossover between queer identity and a cheeky parody of gothic melodrama.

[9] As one of Mike Friedrich's Star Reach regulars, she expanded her writing and art style to include serious fantasy fiction in Stark's Quest (1977–1979), a study of ESP, politics, and social engineering.

Her clients have included Disney/ABC, Apple Computer, IBM, Time Warner Inc., Children's Television Workshop, Nickelodeon, Electronic Arts, and MTV.

Marrs produced the four-page “Equal Rites” for Wimmen’s Comix #8, where female protagonists live in a futuristic world where standards are mono-gendered, and the implementation of the ERA amendment has blossomed; the glass ceiling for feminist stereotypes has been shattered.

"[15] Marrs equates these concrete examples with rejection, for they foreclose the ability of the collective to reach a broader feminist audience despite their varied attempts to participate.
