I read this non-fiction book by Barbara Cartland years ago in a bar that had a book corner for customers. I looked for it for years but it was really hard to track down, eventually my mother found a copy for me and gave it to me as a present.
Other than Barbara Cartland's strange conviction that men prefer women to wear a lot of make-up, the rest of her advice is very sensible and useful. It could hold its own quite happily with most contemporary 'how to make friends and be popular' books.
