Don't know who made the coverpainting. Maybe Edward A. Knapp. Cover photo's by Bill Haman.
This one is from a childrens book.
Cover: painting: ???
The last one is the cover of a book I like very much. It has a lot of photo's and gives an impression of how artists saw aviation in the first part of the century.
