This is page 31 of "Admiral's Winter Vacation", a Kancolle artbook released by the game's creators C2 Architecture. Posting this so that people can see what the Shinano alpha art looks like.
Do we have tags for the artists Youki or Rikka of C2 Architecture?
Oh you have both of those? Absolutely nice, missed out on those two so that thrown off my plan on collecting the books that has the same message to admirals ^^;;;
"We are thankful to all admirals. Bless you and your fleet girls"
