In Vienna, he stayed with a family friend (who had not expected him), studied at the Vienna Fine Arts Academy, and surrendered his passport to seek political asylum as a stateless person. There, he supported himself with commissions and briefly visited Italy with the academy, whose program he found equally unhappy as the one before it. At the behest of a friend relocated from Sofia, he saved up to visit Geneva in late 1957. In violation of his visa, he continued to pursue commissions (whose works he would sign with his family name, reserving his given name for more serious work) and was transformed after visiting the Kunstmuseum Basel and Kunsthaus Zürich. In January 1958, he first began to wrap things, as would become his trademark, starting with a paint can. His collection of wrapped household items would be known as his "Inventory". In February 1958, Christo left for Paris, having received a visa with the assistance of a Sofia academy connection.
