Though I find most advertising that references a tragic event to be pretty distasteful, I also believe that when done in the right manner it can actually be not only respectful but powerful. In this older campaign for the newspaper Cape Times, these ads remind us that our lives can change in an instant and make us appreciate the simple experiences in our everyday lives.
Sunday, 5 August 1956 (day before Hiroshima)
Tuesday, 15 June 1976 (day before ’76 Soweto riots)
Thursday, 21 November 1963 (day before JFK’s assassination) 
Ad campaign by Lowe Bull agency. Also, check out Cape Time’s newest campaign titled Different Angles. Both are pretty brilliant.
