For the first 40 years or so of the 20th Century Dudovich reigned as Italy's foremost poster artist. Reproductions of some of those posters can be found today.
Like his more famous German contemporary Ludwig Hohlwein, Dudovich made use of solid representational bases from which design-related simplifications or elaborations could be created to provide intended visual impacts. Unlike Hohlwein who began his career as an architect, Dudovich had a fair amount of formal art training. Moreover, his style evolved over time, becoming more simplified in the 1930s in line with fashions in illustration and fine art.
A detailed biography can be found here on a Web page devoted to Dudovich. The site includes a good number of examples of his art. Below are works shown there and found elsewhere on the Internet.
