The official artwork for the HBO show, unveiled by Entertainment Weekly ahead of the series' return on March 3, features a flying dragon.
A full-page ad also ran in today's (February 25) New York Times, containing 'news stories' relating to the show's universe.
Speaking of the upcoming season, Game of Thrones star Jerome Flynn recently hinted at conflict between his character Bronn and Tyrion (Peter Dinklage).
"He's just about sticking it with Tyrion," the actor teased. "He's getting a bit frustrated, underpaid.
"He's not got the position he had, but there's still love between them. And some good, some nice scenes together, but not much.
"The writers - Dan [Weiss] and David [Benioff]... they've been great because they've given me bits - even though there's not much in the books - they keep me, keep Bronn ticking along."
