As a struggling artist, Lopez applied for and received grants from the Ludwig Vogelstein Foundation and the Pennsylvania Council on the Arts, each of which gave her $2500 to write. A cross-country motorcycle trip served as inspiration for her first illustrated novel, Flaming Iguanas, which includes numerous images made with rubber stamps and was published by Simon & Schuster. That same year she published a book of cartoon stories called Lap Dancing for Mommy. Lopez went on to publish two additional illustrated novels with Simon & Schuster, They Call Me Mad Dog! and Hoochie Mama: The Other White Meat before her relationship with Simon & Schuster's publisher, David Rosenthal, soured. These three books form a trilogy of very-loosely autobiographical novels which describe the exploits of "Tomato Rodríguez". After a stint on welfare, and while touring her show, Lopez decided that the people in the suits didn't know how to run the arts industries, or the country's economy, and so she decided to take her fate into her own hands and become a "mini-mogul." Along with James Swanson, Kamala Lopez, and Jeffrey Hicken, they started a book publishing company, Monster Girl Media to go along with Monster Girl Movies, as a part of their coalition of Do-it-Yourself businesses in charge of their own development, production, merchandising, and promotion. Their first publication is "The Girl Must Die: A Monster Girl Memoir" along with the matching, "The Girl Must Die: 18 Postcards." They work with a rotating roster of other Monster Girls Mujers and Men like Alison Penton Harper, Bianca Laureano, Kate Gottli, Suzanne Rush, and Peter Maravelis.
Performance art
Lopez is best known for the performance art characters of “Grandma Lopez” and "The Welfare Queen" which she created after she began to receive welfare after her fight with Simon & Schuster. These characters are at the heart of Lopez's performance piece Nothing Left but the Smell: A Republican on Welfare, which she has performed at locations as varied as San Francisco, New York City, Edinburgh, London and Manchester, and Oslo. The text of this performance piece has been published in a self-edited artist edition and is also available online.
