I include posts about lesser artists here because, in part, their work helps to put in context that of the best artists. A feeling for their times is also enhanced by being exposed to their interpretations. Van Buren might best be characterized as a journeyman, given the large number of highly talented illustrators active in the 1920s and into the 1950s.
For non- English-speaking readers, here we have a religious idol and a movie "idol."
