Interesting little book. I'm uncertain whether anyone could learn anything from a book about dance, but used as an aid or reference to enhance live instruction, it might be useful... perhaps. Unfortunately, this fifty page book, which saves it's suggested ballroom routine for pages 31 and following, is printed pages 1 through 30 - the last 20 pages being left blank.I returned one copy explaining how it was defective only to receive another that was exactly the same way. I suspect that all the remaining copies have the same defect, and we could go on and on like this for a very long time.
