It's a bird... It's a plane... It's a picture of your wife on a camel in the Sahara, on a Boeing 737! Dutch airline Transavia recently held a photo competition that we couldn't help but notice. To celebrate its 40th anniversary, the holiday transporter invited passengers to send in pictures taken in or around one of their 87 destinations. Forty winning photos have been picked and will be printed on larger-than-life stickers, along with the photographer's name, and stuck onto several of Transavia's planes.

It's a fun example of using gravanity: the ever-popular consumer trend – and faithful marketing standby – that lets the masses get their names and faces in lights, even if just for a moment. A previous pairing of gravanity and airlines was KLM's create your own luggage tag campaign, which is still running.
