This Painting is Worth 60 Million Yen

Nobita's father meets an old man on the street. They reminisce about the past and the old man tell Nobita and his friends that the old man is Kakihara, his childhood art teacher. The old man shows Nobita and his friends some of his painting from a magazine. They can't understand them. The old man says that his paintings are now worth 6 million yen, but when they were kids, no one wanted to buy them even if they sold them for 100 yen. Nobita and Doraemon feel it is a pity that they haven't brought a painting back then, otherwise they will have made a lot of money. So they ask their mother for an advance of 1,000 yen of New Year's money plus their own savings of 98 yen, and then take the "Time Machine" back to 25 years ago (Showa 24) to buy a painting. When Mr. Kakihara hears that they want to buy a painting, he is moved to tears. He says that because no one believes in him, he is about to give up painting. The two of them tell him that he will become famous in the future, which greatly boosts his confidence. However, when they go to buy the painting, they find that the money is from the wrong era, which makes the teacher think that they are playing a joke with counterfeit toy money. The two return to the present and think they can buy some from Suneo, who collects ancient coins. However, ancient coins are expensive, and they can only exchange all their money for a pittance. They then return to the past. A teenager opens the door, saying the teacher isn't home. They discover he was their father from when they were young and chatted with him. However, he scolds them for saying he can't become a painter. Their father tells them to just pick any painting they want, but after looking at many, they can't understand any of them. They choose the only one they can understand and buy it. Back in the present, they tell their mother the painting is worth 6 million. At that moment, their father sees it and excitedly says it is a painting he had drawn as a child, very valuable as a keepsake, but he has never known where it is. The two then realize they had taken the wrong painting and are very disappointed.
