Moviexclusive.com have posted a very large scan of an advertisement for Harry Potter and the Prisoner of Azkaban. The new poster combines Harry, Ron & Hermione from the posters that we have seen before. It may take a few minutes to load as it is an extremely large poster.
Update: Due to the overwhelming requests from HP fans, Moviexclusive.com is holding a mini-contest to win this piece of newspaper advertisement. (Otherwise, you'll just have to hope it turns up in the stores, or accept the selection that is currently available in the market.) Good luck to those who enter.
