A brief Wikipedia entry on Bradley is here, a link with more detail and plenty of images is here, and a chronology of his life can be found here. He had a long career that involved art direction as well as creating artwork.
Bradley was essentially self-taught, learning his trade on the job. The images below are mostly or entirely from the late 1890s. If I eventually find enough interesting illustration art from later in his career, I'll post on that.
Plenty of Art Nouveau swirls here.
This has more of an Art & Crafts feeling.
Although motor cars existed in 1895, bicycling had become popular due to the invention of the bicycle chain drive.
A faint hint of Aubrey Beardsley here.
This seems strongly influenced by Beardsley.
