Question: How old was Mieszko when he died? Passage 1:Gradually, the size of the issues was decreased as the publisher was reluctant to raise the cover price from the original 10 cents, so there were fewer stories. For a while, Congo Bill and Tommy Tomorrow were the two features in addition to Superman. Writer Robert Bernstein and artist Howard Sherman revamped the "Congo Bill" backup feature in issue #248 (January 1959) in a story wherein the character gained the ability to swap bodies with a gorilla and his strip was renamed Congorilla. The introduction of Supergirl by Otto Binder and Al Plastino occurred in issue #252 (May 1959). Following this debut appearance, Supergirl adopted the secret identity of an orphan "Linda Lee" and made Midvale Orphanage her base of operations. In Action Comics #261 (February 1960), her pet cat Streaky was introduced by Jerry Siegel and Jim Mooney. Supergirl joined the Legion of Super-Heroes in issue #276 and acted for three years as Superman's "secret weapon," until her existence was revealed in Action Comics #285 (January 1962). In the view of comics historian Les Daniels, artist Curt Swan became the definitive artist of Superman in the early 1960s with a "new look" to the character that replaced Wayne Boring's version. Bizarro World first appeared in the story "The World of Bizarros!" in issue #262 (April 1960). Writer Jim Shooter created the villain the Parasite in Action Comics #340 (Aug. 1966).
 Passage 2:Mieszko I, Duke of Cieszyn, the first ruler of the duchy, died in 1315 and afterwards his sons divided its land into two parts alongside Biała River: diminished Duchy of Teschen to west and Duchy of Oświęcim to east. In the middle of the 15th century Duchy of Oświęcim was bought into the Crown of the Kingdom of Poland and so the river constituted henceforth the border between Polish and the Bohemian Crown (since 1526 part of the Habsburg Monarchy). Upon the First Partition of Poland in 1772 the river ceased to be a state border and continued as a regional border between Austrian Silesia to the west and Galicia to the east. After World War I and the 1919 Polish–Czechoslovak War it separated the Polish part of Cieszyn Silesia in the Autonomous Silesian Voivodeship from Lesser Polish Kraków Voivodeship.
 Passage 3:Fago was born in 1914 in Yonkers, New York, of parents who had immigrated from Naples, Italy. He had two sisters and a 10-year-older brother, Al Fago. At 14, Vincent Fago sold his first cartoon to the New York Sun, for $2. He attended DeWitt Clinton High School in the Bronx, graduating at age 20, he recalled in 2001, after encountering difficulties upon losing vision in one eye at age 16. By this time he had begun work as an animation tracer at Audio Productions in the old Edison studios in The Bronx, and advanced to become an in-betweener after the company moved to the Fox Movietone News Building. He then worked four years at the Jam Handy Studio in Detroit, Michigan, contributing, he said, to "films for Chevrolet, and stop-motion pictures, and Technicolor films for the Metropolitan Life Insurance Company. From there, he spent four years in Florida as an animator at Fleischer Brothers Studios, where he worked as an assistant animator on Betty Boop, Popeye and Supermantheatrical shorts and on the animated features Mr. Bug Goes to Town and Gulliver's Travels.
