Hand-drawn illustration and signature by Yoichi Takahashi, the author of "Captain Tsubasa," "Sho no Densetsu," and "Ace!" The character is Satoshi Nakamoto from "CHIBI." I obtained this previously from another site, and the previous seller stated they received it directly from the artist at an event. Please note that I have not had it authenticated. While signatures from Captain Tsubasa are common, signatures from CHIBI are quite rare. There is some wear and tear from age (small dents on corners and edges, some yellowing), but there is no particularly noticeable damage, and overall, the condition is considered to be above average for an old item (in my opinion). Also, please refrain from extreme price negotiations. As a bonus, I will include a Captain Tsubasa clear file, pencils, pens, and a ruler (all unused, but as they are old items, I cannot guarantee the usability of the pens, etc.). Please refrain from purchasing if you are overly concerned about the condition, do not read the description, do not ask questions beforehand, and then complain after receiving the item, saying "it's not what I expected." Please ask any questions you may have. (Please understand that I cannot answer rude questions.) Thank you.
