This is a signature from Hiromasa Yonebayashi. I heard from my father that he won it in a radio prize 15 years ago. There's also the bag with the original shipping tag that the shikishi (autograph board) came in. The Arrietty in the center looks printed, while the surrounding flowers, grasshopper, and signature are handwritten. Please feel free to comment if you have any questions. I can add more photos if needed. #HiromasaYonebayashi #Ghibli #TheSecretWorldOfArrietty #HayaoMiyazaki #Signature
