Famous Painting Checker
While Nobita and his friends are at Suneo's house admiring Pablo Picasso's paintings Suneo's father bought, Nobita observed the most expensive one and finds it similar to one he drawn in the past, to which Suneo rebuked. After finding the drawing, Doraemon assumed he copied the work of Picasso's, but Nobita insisted that it is coincidental that both are similar. Doraemon decided to check for the sendimental value using the "Famous Painting Checker". After screening the drawing, the machine explained that it is worthless in the future, but very valuable in year 1944's Europe. As there is no such painting then, Nobita decided to take the drawing to that era despite the ongoing World War II then. Once they reached 1944's Europe, they saved a girl, who turns out to be Picasso's granddaughter, and reveals that Picasso was forced to draw a painting by a Nazi soldier in his mansion. Doraemon eats “Hitler's Pills" which gives him the authority to order the Nazi soldiers to leave. Nobita's drawing was discovered by the girl who claims that it is drawn by her younger brother, Tonio, who was killed in a blast sometime ago, and Picasso stopped drawing since then over the loss of his grandson. Upon seeing the drawing, Picasso picked up the paintbrush and made some adjustments to the drawing, the end result of which resembles what Nobita saw of Picasso's painting in Suneo's house. He explained that Tonio drew a similar work at the age of three, and Nobita's drawing helped him to revive the passion of drawing. The episodes end with Nobita drawing Shizuka in Picasso's style, thinking in his mind that it is him who originally produced Picasso's main drawing.
