An odd intermittent trend is for some female writers to appear nude on the front of their own books.
My first thought would be that this would be to get male readers to buy the books, but then some of these books are aimed almost entirely at women (except for the Pamela Anderson "novel", the target audience for which is utterly mystifying). I can't think of any books by men where the authors pose nude on the front. Can anyone out there suggest any?
Female nudity on book covers is, of course, very common (see an earlier discussion here). Male nudity, aside from photos of Michelangelo's 'David' or the covers of romance/porn novels, is almost non-existent. Yet we're frequently told that women buy most books.
While we're on the topic, certain images used on book covers discussed in earlier nudity-themed posts have cropped up again elsewhere.
Here's Ben Stockley's photo from the York Hall Russian Baths (discussed here) on four covers...
..and another photo (first discussed here) on three.
It should be noted that Ediciones Nowtilus are more scared of pubic hair than some other publishers.
