Winning numerous prizes for her works, she has four landscapes in the permanent collections of the National Art Gallery in Caracas and is remembered as an important South American graphic artist.

[1][2] She studied at the Academy of Fine Arts, with her sister Maria Luisa Zuloaga de Tovar, under the tutelage of the Catalan artist, Ángel Cabré y Magriñá.

[4] In 1950, Zuloaga returned to New York City to study engraving, taking courses with both Johnny Friedlaender and Stanley William Hayter.

She was particularly influenced by Hayter's method of color printing often utilizing numerous layers of pigment and burnishing techniques to achieve her desired result.

[8] Pilar Muñoz López, a professor and art critic at the Autonomous University of Madrid, has named Zuloaga as " one of the most important graphic artists in South America".
