London poster

I can't help thinking, "did they mean to put 'and' twice?" If they did, why did they? And what is it supposed to mean anyway?

When I was little, trips to London would always scare me, precisely because of posters like this. I used to stir myself into a mild panic, trying to work out the meaning of statements on walls. I'd wonder about the ferality of the minds who thought them up. The city was a wild place, breeding even wilder brains spewing out wild thoughts. London was fear and desire, as far as the eye could see.
