Huffpost Celebrity has a nice slideshow of actors who’ve modeled for book covers. Amanda Seyfried, Brooke Shields, and Matt Bomer have all appeared on book jackets but our favorite in the lineup here is Blondie rocker Debbie Harry, whose head – and only her head - appears perched over a box of chocolates on the cover of Josephine Tey’s The Franchise Affair (1971).
