Hetalia art book?

[tsukisprite.livejournal.com]

Hi guys....I've recently gone to an anime convention and purchased a hardcover artbook that has official pictures and special bonus fanart/ doujinshi pictures. What I'm curious is is this book official merchandise or is it a bootleg type of thing? I'm sort of guessing it's a bootleg because all the letter characters on the cover do not seem to have any of the Japanese particles...Please correct me if I'm wrong....

Nice book but yeah...I'm just a little concerned.
