The three posters for Sergio Corbucci's Giallo Napoletano. The top poster and the title are a bit misleading since the film is more a comedy with thriller elements rather than a giallo. The last and third one even includes a picture of Hitchcock to push the the thriller aspect of the film. I have to say that I was pleasantly surprised by it the first time I saw it though. Marcello Mastroianni is great as the hapless mandonlin player Raffaele drawn in to a murder mystery. No info on the poster artists.
