You can file the following as fan art. Just found out from someone who actually got the DVD and CD and the insides are just plain white. How disappointing! Fans should be the one to design cover arts because the fake ones were awesome, totally!
The following are the inside art of the various versions for THE BEST BANG!! album to be released on 17.11.2010. Thanks to River of MashaPlus Info Forums for reposting these. All are same except for Disc 3 with 3 versions (different song titles but same image) depending again on which version you bought. For the cover versions, click here. For the song list, click here. For the CM voiced by Masha himself, click here. By the way, original pictures used for the cover art is also included, thanks to AngelReii of MashaPlus Info Forums for her sharp observations.
