sentences:  Ruth K. MacDonald, author of "Beatrix Potter" (1986), believes the success of "The Tale of Two Mice" lies in the plentiful and meticulous miniature details of the doll's house in the illustrations.Potter persistently and consistently pursued a mouse-eye perspective and accuracy in the drawings.She could not have clearly seen the staircase down which the mice drag the bolster because it was impossible to take a photograph at that location, yet she placed herself imaginatively on the staircase and drew the mice in anatomically believable postures and in scale with the features of the doll's house.
