To promote the release of a special interest book, Forensics by Val McDermid, Jack Arts targeted two events. One at the Natural History Museum and another at the Wellcome Collection. Jack actors in forensic suits engaged with attendees of the events by handing out postcards and asking forensic questions to enable them to potentially win a copy of the book. Which was of course, in an evidence bag. We also ensured both these locations and nearby transits were plastered in static clings promoting the book. The repeated image of the fly proved incredibly striking and worked exceptionally well. Generated great content, activity re-tweeted by the publisher and the author’s thousands of followers too.
