Sándor Benkő was a great master of Hungarian poster art. He produced most of his designs from the early 1960s until the late 1980s. He specialised in circus poster design, of which he is most famous for. His cheerful and expressive style was also well suited for movie and theatre posters.

In 1940-1941, he received private training from István Örkényi Strasszer, János Rozs and Ernő József Deutsch. Between 1947 and 1955, Benkő worked in the studio of László Muskovszky. After 1955, he became an independent designer, creating illustrations for important publishing houses, slide films, demonstration boards for the army, and graphic designs for fairs and exhibitions.
