As if seeing two episodes of HBO's Game of Thrones on the big big screen wasn't enough, IMAX has debuted two exclusive posters that will only be available to the first 300 IMAX ticket holders present at the premiere showing on Jan. 10.

The posters, created by illustrator Robert Ball, are titled "The Watchers on the Wall" and "The Children." Only the lucky first 300 at AMC theater screenings will receive the "Wall" posters; all other IMAX locations will have "The Children" commemorative poser.

Due to what HBO called "unprecedented fan enthusiasm," the IMAX presentation of the final two episodes from Game of Thrones' fourth season was bumped back a week to Jan. 29. The special event will now unfold in 200 IMAX theaters across the country and run through Feb. 5.

Tickets for the event go on sale today for screenings in a number of cities, including Atlanta, Boston, Chicago, Dallas, Denver, Houston, Las Vegas, Los Angeles, Miami, Montreal, New York, San Antonio, Seattle, Toronto and Washington, D.C.

If you're not one of the first 300 people in line at an IMAX theater on January 29, you'll at least get to enjoy the limited edition posters via the internet. You can check out both posters below -- but be careful, because one contains a major spoiler.
