Face it… Just starting to make their way around town and online, HBO has released 12 captivating new posters of the familiar “Game of Thrones” cast members, half bathed in darkness. The imposing new promotional images launch outdoor (we like the strategic use of long outdoor spaces to show all 12 posters) and print ad campaigns next week ahead of the “Game of Thrones” Season 3 premiere on March 31. They follow the release of the first full length trailer and an online ad campaign running on the New York Times and several entertainment sites. With success obviously comes larger promotional budgets. Thank the almighty king(s) for that…
