Girl at Mirror follows a long tradition by fine artists of picturing a woman contemplating her reflection. George Hughes said that a painting by Edouard Manet inspired this painting. Two paintings by other artists stand out as strong candidates, however. Included in Rockwell's reference files are examples of Picasso's Girl at Mirror and Elizabeth Vigee-Lebrun's The Artist's Daughter, each of which could have directly influenced this work.
