Stewart Rouse was an illustrator who was active in the 30s and the 40s.  The majority of his work appears to have been done for aviation and car magazines and he also served as a staff artist for Popular Mechanics.  According to a brief bio that was published in a 1946 issue of Popular Science Magazine, Rouse was trained at the Chicago Institute of Art and “once built a homemade airplane that a harsh government refused to let him fly.”

Below are a few of Rouse’s covers, along with some illustrations that he did for an article on how to take care of a car.  The covers are from the 30s and the illustrations appear to be from the 40s.
