I want to bring to your attention a new book by a friend of mine; we went to graduate school together at the U of I.  The book—Lydia Pinkham: The Face that Launched a Thousand Ads by Sammy R. Danna (Rowman & Littlefield, 2015)--is about Lydia Pinkham, her vegetable compound (which is still being sold), and the revolution in marketing and advertising of which she was a major part.  Congratulations Sam; you did a wonderful job!
