There is no other way, probably, to advertise a crime and detective bookshop effectively. The advertisement campaign interestingly used the cover page of some famous books such as The Old Man and the Sea of Ernest Hemingway. The ad shows how the people on the cover page becoming victim to a crime.
The art direction of the campaign is perfect in line with a remarkably fresh idea for the advertisements. However, the copy of the campaign, Intruders not welcome, is somewhat deviating from the core idea of the advertisement. The advertisement campaign is credited to JWT, Barcelona, Spain.
