It's Hard to Classify Will T. Bradley
Will T. Bradley (1868-1962) was the highest paid American artist in the early 20th century*, but don't feel bad if you haven't heard of him.
At a time when magazines were the chief vehicle of cultural expression, Bradley was a prolific and noteworthy cover artist.
His style featured simple shapes, smooth lines, and large areas of flat colors, which lent itself not only to covers, but also to posters.
When he wanted to, he could draw in a more ornate pen-and-ink style, influenced by Aubrey Beardsley and Alphonse Mucha.
Bradley was a type designer he created the original version of what is now known as Bradley DJR (designed by David Jonathan Ross.) And he was also an art director for Hearst films.
