From my last trip, I brought a NO NAME's signle CD, which looks like this:
On the left is a pack-in bonus: a photograph of... someone. Ditto on the right. Despite studying printed material, I continue to be confused by 3D, so I cannot tell. Logically thinking, it should be Mayuyu and Karen Iwata on the cover. By an inhuman effort I started to recognize the latter somewhat, mostly thanks to her smile being a little shy, but the girl on the left looks nothing like a Mayu Watanabe... I think. As for the photo, it could be Mao Mita, who is just a tad chubby.
UPDATE: No, the material has no captions. Not the CD booklet, not the pack-in photo. The pink print on the photo is a copyright statement.
