Apparantly this ad has a message - but I only found that out from an article in the papers!
As for the advert its self, I've only seen it once, and once was enought, as its so wrong!
With the telescope the girl has, she wouldn't see so close in to the moons surface, and with the telescope the man gets he'd see even less.
All that on top of the fact there's no atmosphere on the moon, and no ballons would escape the Earth and make it all the way to the moon.
Its just so wrong!
