After graduating from the Nicolae Grigorescu Institute of Plastic Arts, Irina Georgeta Pusztai started making cover illustrations, especially for the publishing house Meridiane. She was then asked by writer and architect Kos Karoly (1883-1977) to make a comic adaptation of his historical novel 'Varju Nemzetseg'. The book was published in 1976 by Ion Creangă and it has remained the artist's sole comic to date.
Pusztai and her husband emigrated to Switzerland in 1981, and settled in Montréal, Canada, three years later. She has continued to work as an artist for advertisements and publishers, and her paintings have been regularly exhibited in Europe and Canada. Her work has been featured in the magazine Graphis on several occasions.
