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to exploit the commercial possibilities of her characters and tales with spinoffs such as a Peter Rabbit doll , an unpublished Peter Rabbit board game , and a Peter Rabbit nursery wallpaper between 1903 and 1905 .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