Advertising Today and Tomorrow (RLE Advertising) [PDF ebook] 

Advertising Today and Tomorrow surveys the structure and function of modern advertising (and in particular the modern advertising agency), investigates how appropriate its machinery is for modern business requirements, and suggests how, both for the good of itself and its clients, it can best equip and refine itself for the future. It is of great use to students of business, particularly of marketing, in the colleges, universities and business schools, as well as being of great help to young people seeking to make advertising their career.
