First Fifty Shades of Grey Poster revealed

The first official poster for Fifty Shades of Grey has been revealed.

And it's probably classier than you were expecting from the mummy-porn S&M literary phenomenon.

While the book concerns itself with whips, chains and the - ahem - 'red room of pain', there's nary a lubricant in sight in the first official teaser poster, which has debuted over at Entertainment Weekly.

In fact, all you get is a teasing strapline, and Jamie Dornan's besuited back. And as backs go, we suppose it's at least a sexy back. So well done there.

Anyway, check out the poster below and then let us know what you think in the comments section underneath.
