Peter Rabbit
Potter confidently 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 She was the first to exploit the commercial possibilities of her characters and tales with a Peter Rabbit doll, an unpublished Peter Rabbit board game, and a Peter Rabbit nursery wallpaper between 1903 and 1905. Similar "side-shows" (as she termed the spinoffs) were produced over the following two decades.
