Slam Dunk is a basketball manga by the great Takehiko Inoue, who is also well-known for Vagabond and for designing the characters for the game Lost Odyssey. The last post featuring Slam Dunk was really about featuring yaoi artist Yamane Ayano's doujinshi artwork. This time, however, it's all about the official art.
Although it was turned into a long-running anime series, there is no anime art in today's post. Only Inoue's illustrations are featured this time around. The original manga is currently being released in America by Viz Media. I'm not sure about the status of the anime.
