In order to promote its assortment of horror literature for Halloween, these book advertisements from Libri Mundi turn the spines of books into scary characters.
The print ads feature the faces of a skull and a vampire that have been made up of vertical, horizontal and slanted books. Depending on which way the spine of the book has been oriented, the coloring of the Halloween icon is slightly different, forming eyes, teeth and noses. Since it's not always easy to communicate the kinds of scares that you can kind in a good book, these ads are a clever way to suggest the creepiness you'll get in-store. As well as making pretty creative print ads, replicating these shapes would make a fantastic storefront window display in a bookstore.
