Her outstanding works are the art deco graphics and paintings created in the twenties and thirties, several of which are owned by the Hungarian National Gallery.
In 1914-15, she won a silver medal with her work at the world art exhibition held in San Francisco on the occasion of the opening of the Panama Canal.
According to her daughter's recollections, in the summer of 1924, while walking with a friend in Városliget, her mother got into a conversation with two young men, one of whom was 19-year-old Attila József.
After that, he visited the Gyenes family many times, during which she bantered with him as well as developed a playful friendship with the poet, without any real love in return.
In the following years, József Attila was often a guest at the Gittas - who was a mature beauty and an attractive artist at the time -, among other things, in the framework of the Gyenes Literary Salon organized in their apartment, where he, Kosztolányi, Karinthy, Kassák, Faludy, Tersánszky and others read their writings.
Attila József, Dezső Kosztolányi, Frigyes Karinthy, György Faludy, Lajos Kassák and Jenő Józsi Tersánszky were the central figures of the salon's reading evenings.
