In 1951 he traveled to Paris, where he remained for three months and then moved to the Balearic Islands, where he lived until he returns to Venezuela.

In 1969 he exhibited at the IDB in Washington. The style and theme of Petrovszky have been invariable for years, despite the rise of movements such as geometric abstractionism and informalism. The artist focused on a work of figurative character that represents man and his city, always in a cold and austere atmosphere that indicates loneliness and loss of communication. 

He presented four solo shows at Galeria Medicci since 1998: Escena Silenciosa; Saga sin fin; Mirada Reflexiva and Escena Cotidiana
