It's too early for this kind of news!
Paul Webster reports in the Observer - Parisians get order to smile:

There won't be much point in asking the waiter to say 'cheese' for those souvenir snaps in Paris this summer. He has already received orders to smile like mad at foreigners as part of a courtesy campaign.

Worried that tension between France and the Anglo-American coalition will lead to hostility at street level, the Ile de France region, which covers the 10 million people in and around the capital, has launched a campaign for locals to be nice to foreigners.

Thousands of posters of happy Parisians in which every figure is decorated with a cartoon 'smiley' have been put up, promising visitors that in the Ile de France, 'our smiles come from the heart'.

Hmmm, why am I suspicious?

There is nothing in the campaign that bans pulling faces behind customers' backs, as Anne Preghon, salesgirl in a big department store, pointed out.

'Why should Parisians be nice to foreigners when they are not even nice to each other?' she said, smiling.

Now that's more like it! Sorry, no poster links, but I'll keep looking. I suspect they are all on eBay as rare collectibles.
