Who let the cat in? A blinder of a strap line from Wolverhampton City Council celebrating investment from Jaguar Land Rover.

In the competitive advertising and marketing world you really need a splash to catch the eye. Most ads just pass over you.

The private sector has the finance and time to buy in the consultancy necessary.

Councils tend to have a back seat when it comes to the creation of interesting copy for marketing their activities. Not so here.

Came across a startling item in the street today which caught the eye. An in-house creation from Wolverhampton City Council, celebrating the investment of Jaguar Land Rover in its new engine plant on the M54.

This is a city looking for all the good news it can get and the council have come up with a blinder here. "Who let the cat in?" is simple, succinct and savvy.

What makes it good? The initial question-answer device followed by the allusion to the Mafia offer for starters. Company logo and the courage not to use all of the space add a further dynamic.

Finally, the bracketing of the whole ad with the puzzle-solution rhetorical device highlighted in yellow is simplicity itself. This is an ad which really works and someone should be putting it up for an award.
