Mead Schaeffer (1898-1980) is one of my favorite illustrators. I wrote about some of his works here, here, here and here.
Now David Apatoff, America's leading illustration maven, has a book about Schaeffer due to appear in July. The cover is shown above, and information regarding it can be found here. Of course I ordered a copy and eagerly await it.
As I wrote here, Schaeffer claimed that he was happy to move from his signature period-piece illustrations so as to portray contemporary scenes. My take then and now is that his early, pre- World War 2 illustrations were his best. I suspect Apatoff agrees, because the book's cover art is from that earlier career phase and not one of his later works.
A few examples indicating Schaeffer's stylistic evolution are shown below.
