Amnesty International hopes to attract members with a stark new ad by Bates Backer & Spielvogel, Oslo, Norway. The ad, which broke Aug. 25, features the words "Talk here" superimposed on the barrell of a gun. The copy translates as "More and more people find it impossible to exercise their freedom of speech. That's why it's more important than ever that you are exercising yours." A toll-free number follows. Aris Theophilakis was both the art director and copywriter. The ads are running in newspapers nationwide in Norway.
