ピーターラビット
Potter asserted her tales would one day be nursery classics, and part of the process in making them so was marketing strategy. She was the first to exploit the commercial possibilities of her characters and tales with spinoffs such as a Peter Rabbit doll, an unpublished Peter Rabbit board game, and Peter Rabbit nursery wallpaper between 1903 and 1905. Similar "side-shows" (as she termed the ancillary merchandise) were produced with her approval over the following two decades.
