The ARENA TOUR 2006 posters were indeed that photo and the close up on Ayu's face.
I believe they'll be on the mu-mo ordering page until stock runs out.

If you really want them, I would order from fdjp. He charges standard EMS shipping and a 3000yen commission for orders under 10000yen. [over 10000 or 10000 exactly is 30% commission].
