poetry collection When We Were Very Young (1924) was a success. The illustrations were done by artist and fellow Punch staff E. H. Shepard. Among the characters in When We Were Very Young was a teddy bear that Shepard modelled after one belonging to his son. With the book's success, Shepard encouraged Milne to write stories about Milne's young son, Christopher Robin Milne, and his stuffed toys. Among Christopher's toys was a teddy bear he called "Winnie-the-Pooh". Christopher got the name "Winnie" from a bear at the London Zoo, Winnipeg. "Pooh" was the name of a swan in When We Were Very Young. Milne used Christopher and his toys as inspiration for a series of short stories, which were compiled and published as Winnie-the-Pooh. The model for Pooh remained the bear belonging to Shepard's son. Winnie-the-Pooh was published on 14 October 1926 by Methuen & Co. in England and E. P. Dutton in the United States. As a work first published in 1926, the book entered the public domain in the United States on 1 January 2022. British copyright of the text expires on 1 January 2027 (70 calendar years after Milne's death) while British copyright of the illustrations expires on 1 January 2047 (70 calendar years after Shepard's death). Stories Some of the stories in Winnie-the-Pooh were adapted by Milne from previous published writings in Punch, St. Nicholas Magazine, Vanity Fair and other periodicals. The first chapter, for instance, was adapted from "The Wrong Sort of Bees", a story published in the London Evening News in its issue for Christmas Eve 1925. Classics scholar Ross Kilpatrick contended in 1998 that Milne adapted the first chapter from "Teddy Bear's Bee Tree", published in 1912 in Babes in the Woods by Charles G. D. Roberts. The stories in the book can be read independently. The plots do not carry over between stories (with the exception of Stories 9 and 10). In Which We Are Introduced to Winnie the Pooh and Some Bees and the Stories Begin: Winnie-the-Pooh is out of honey, so he tries to climb a tree to get some, but falls off, bouncing on branches on his way down. He meets with his friend Christopher Robin and floats up with a balloon of Christopher's, only to discover they are not the right sort of bees for honey. Christopher then shoots the balloon with his gun, letting Pooh slowly float
