Roll up, roll up, for the brand new and rather spooky looking international teaser posters for Harry Potter and the Half-Blood Prince. In one shot, Potter sports a rather nifty pair of special edition Dumbledore glasses. The the other two pictures show Harry with wand in hand staring in the face of danger, and Dumbledore stood beard flowing - ready for action.
**Harry Potter and the Half-Blood Prince **is due in UK cinemas July 17.
