My friend Nancy introduced me to a new* book-related blog this week...
Judge a Book by its Cover.
Its authors showcase amusing, crazy, over-the-top, and downright horrible cover art with commentary. They have recurring features like "Mammary Mondays" and "Phallic Phridays." Check it out, Judge a Book by its Cover is definitely worth a look.
* not new, but new-to-me. Here's a link to the blog first post from March 2007.
