Modern Business best Textbooks from 1930's Alexander Hamilton Institute- Advertising & Marketing

best Set of 3 vintage mail order textbooks from the Modern Business course from the Alexander Hamilton Institute. The copyrights are from 1926-1930. At this period of American history, mail order courses were popular. You would pay for a course and materials, the books were mailed to your home, and there were exercises/exams that you would send back completed in order to get a certification from the course. The books included in this set are: Advertising Campaigns by Bernard Lichtenberg;Advertising Principals by Hugh E. Agnew; and Marketing by George Rowland Collins.

All are imitation leather softcovers with the same embossed design of the Modern Business course. The titles of individual books are in gold on the spine. All three books are in very good or better condition with very little wear to spines and corners. Binding is intact, no rips tears or missing pages. The Advertising Campaigns book has a neat fold-out flow chart, which is still in excellent shape.
