I mention it because Louise Brooks appears on the cover, and there is a two page spread inside devoted to the actress. I had a chance to see a copy of the book recently at the bookseller's convention in Washington D.C. It may or may not be a German release, or a bilingual edition. I am not sure. The author is Claudia Lanfranconi, an art historian and author. The publisher is Merrell.
Needless-to-say, the cover bears a strong resemblance to an earlier release on the same subject, People & Pearls, which was published in 2000. What's better than one book on pearls with Louise Brooks on the cover? Two books!
