Looks like apart from the poster print, there are FIVE jacket covers for "Best Finger".
(1) pix found on the net:
(2) it’s mentioned in here.
Mentioned here is the second day of "Empress" DVD and "Best Finger" CD ranking oricon daily chart too.
・11Jan = 22
・10Jan = 1 ^^v
・11Jan = 5
Guess both recording companies put in more promotion effort this time. Also the gimmick, such as giving away free postcard, having different cover art, Faithway-exclusive edition, help to boost sales.
Hopefully these releases can make it into the top 20 on the monthly chart and sales can be above 10,000 each (-qp-)
PS: I like the yellow palm best ^^
