I've checked the e-mail addy and it exists.
There's an attaching website
www.production-response.co.uk which belongs to the Fusion Group who are apparently the UK's largest premedia group and provide marketing and advertising services to a wide range of clients.
If it's genuine I dare say we'll hear more about the project from other sources.
In any case there's nothing to lose in sending a photo methinks if there's a possibility it'll appear on an ML poster.
