Roberts painted landscapes, genre scenes and portraits with a nice, clean touch most of the time. To me, the archetypical Roberts painting combines fairly thinly painted backgrounds and more heavily painted subjects with areas done using a broad, flat brush. It seems that around 1910 he began using a more simplified palette. Unfortunately, I can't readily locate many of examples of this new direction. In any case, I find Roberts' body of work from the late 1880s and through the 1890s quite satisfying.

Yes, Roberts also portrayed men.
This was painted when Roberts was simplifying his palette.
