He designed his first known printed posters with János Sebes in the 1930’s, they worked together during this time.
He worked during the late 1940’s and adopted the social realist style in the 1950’s. Most of his designs of this period show the strong influence of Soviet poster art. He worked together with Tibor Bánhegyi on many poster designs. Most of his posters were made for state propaganda.
In the 1960’s Czeglédi’s style changed again, and he started to create modern compositions. He designed a lot of travel safety posters, often using the techniques (photomontage) the colours (red, black and white), and typical compositional tools of the classic Avant-garde. .
