Let's proceed further:
~ Bonus picture for "Finest" album version, the one which got released on "Halloween". It's a good one, since Old and Tatsumiya are featured in a full size.
~ The file is named "Jewelry Box". And this one particularly — "Jewelry Box of Chaos" is mentioned even in the album's nаme. So it's something like an embodiment of the album in a picture form, or just an album's emblem/sigil, lol.
