Not a sneak preview, but something potentially just as cool. The Studio Booth, a company specializing in “multidisciplinary event photography company specializing in customized interactive photo experiences”, has tweeted that they’re going to be at Wondercon in San Francisco from April 1st to April 3rd, and they’re clearly going there on behalf of HBO to promote Game of Thrones.
Looking at the Exhibitor’s List at the Wondercon site, we notice HBO is listed as having booth #341, so we’re guessing where that’s going to be. In the S.F. area, or planning to be at Wondercon? Go check it out and report back!
Edited to add: Someone working at Wondercon—probably in getting it set up for tomorrow—has spotted the Iron Throne!
