[Delirium-Zer0]

We wouldn't be able to tell without seeing the back or the spine, or at least knowing the stock number. The front looks like the real thing.

Norrel: The obi spine on the real JP version has a white background as well. The stock number would be the best way to tell for sure.

Judging from the front, the release it COULD be is the Alion International bootleg, which is close to the non-limited japanese release in how the back looks. But without the stock number or an image of the back that includes the record label logo, it's too hard to tell. Ask the seller for a photo of the back, or at the very least for a stock number. We can tell you based on that. ^_^

Here's a pic of the "I am..." album with the limited edition (and from what I can see, more common) obi... http://page7.auctions.yahoo.co.jp/jp/auction/g42201029

Here's the album with the non-limited, regular size obi (unfortunately I can't find a photo better than this)... http://page5.auctions.yahoo.co.jp/jp/auction/e55604615
That normal-size obi is what the Alion International version has always had, but without the logo for either Alion or Avex, you can't tell which is which.
