This is my 2d One Piece wall calendar, the previous one was from 2011, and they are as gorgeous as ever!
It's pretty big (45x66cm), well printed on heavy card stock paper. There is 1 page for 2 months + 1 cover + 1 extra textless illustration at the very end (that's pretty much a poster to use for when you finish the calendar), for a total of 8 pages of pure happiness!
It's pretty hard to get bored with One Piece artworks, as the are pretty much all very uplifting, funny and colorful, with tons of little intricate details.
I can't see how any fan could ever regret purchasing it. I definitely recommend~
