As One Piece fans are aware, every year, Oda has a tradition of sketching One Piece postcards dedicated to his devoted fan base.
The official twitter page for One Piece posted Oda's artwork. The illustration sees Luffy in his iconic outfit and hat hanging out with Mansherry and enjoying the New Year to the fullest. It should be noted that, this being the year of the rat, the One Piece heroes reflect that in the mouse ears, snout and whiskers.
