101 Places to See

101 Places to See was a book owned by Clara Oswald. She planned to use it for travelling after she finished university, but, when her plans changed and she became a nanny for old family friends, she kept the book as a reminder that she still planned to go to those places. Inside, she kept a large maple leaf that she referred to as the first page. (TV: The Bells of Saint John)
