Diary: Worth leaving home for

If there's one thing that is likely to send an audience to sleep, it's a talk about outdoor advertising.

But Diary is pleased to give you a heads-up on one you may actually stay awake for. The creative legend Dave Trott is going to let us in on the dos and don'ts of creative in outdoor advertising. And he'll be ably supported by Wonderbra, or the brand's "hello boys" campaign, at least. Trott will use this iconic ad and other winners from Campaign's Outdoor Hall of Fame to illustrate how to make outdoor ads worth leaving the house for. His talk, organised by the Outdoor Media Centre, is on 13 September at the ICA in London.
