Don't you just love it when advertisers get creative? "Great minds think alike" boasted this old ad from Ermenegildo Zegna - same paper, same prototype Wall Street men, same suit brand - but The Economist begs to differ "Great minds like a think" - which the magazine supplies with abundance. Fern Hill School went for "Great minds don't think alike" - there, that's critical thinking for you. And the newest addition is for Advertising Week Europe "Great minds think unalike". Indeed, they do!
