Famous korean illustrator Kim Jung-Gi signed and sketched one of his sketchbooks for Oda.
Kim Jung-Gi got famous for his particular style, his crazy perspective and speed and everything without an under-sketch. His fame mostly boosted through youtube in the past years, where famous western Artist took notice of him and kept inviting him to events to the west. He's well beloved by many fans, but even more by many artists. He's friends with Otomo Katsuhiro and Terada Katsuya (released a book with him, same guy who did a cover for the Acel Novel Vol. 1), and many people say Kim Jung-Gi reminds them of Moebius. His sketch for Oda was made at Kaigai Manga Festa in Tokyo - but I have no idea wether Oda went there in person or not. But it's still interesting to see that Oda seems to be a fan. Maybe KJG will do an illustration for one of the future novels.
