As a reward he obtained the Paris scholarship of the Ministry of Religious Affairs and Public Education. He sojourned in Paris between 1925 and 1927. He was a core member of the New Society of Artist and a founding member of the Association of New Artists, whereof he later became vice president. He was also a correspondent member of the Vienna-based Künstlerbund Hagen. In 1930 he had a comprehensive exhibition in the Ernst Museum (jointly with István Biai Föglein, Ákos EcsÅ‘di, Imre Márkus and JenÅ‘ Szantrucsek). He was regularly present at the exhibitions of the New Society of Artists and the Association of New Artists. His works were selected for display at representative Hungarian contemporary exhibitions in Düsseldorf, Frankfurt, Bochum, Warsaw, Krakow, Florence and elsewhere.

His works are characteristically rich in colours, decorative and convey postimpressionistic tone. For a while, he was preoccupied with expressionism, and in the early 30s surrealistic elements started to emerge in his paintings, too.

In 1959 an exhibition was organised from his works in the Ernst Museum (jointly with JenÅ‘ Gábor, Józsa Járitz and István Csillag). He had collected-works exhibitions in the Vigadó Gallery in 1990 and in the Csók Gallery in 1993.

He won a Lake Balaton scholarship in 1938 and 1939 and a Transylvania scholarship in 1942. The watercolour prize of the Ernst Museum (1925), the painters' prize of the Association of New Artists (1928), the painters' prize of the competition organised by the Hungarian daily Budapesti Hírlap (1930), the prize of the exhibition of 'City Images' (1940) and the star order decked with a gold wreath (1990) all testify to the acknowledgement and prestige of Klie's painting career.
