Blue-colored illustration of woman with bob haircut holding a hand mirror up to her face. Red scalloped border around edge of button on a white background.
Through the 1940s, pocket mirrors were a popular advertising opportunity, given that the back of the mirror would be on display whenever the user pulled it out in public to check their reflection. Today, unusual and inventive mirrors can frequently be sold at auction for hundreds of dollars to collectors.
This art deco illustration, taken from a popular mirror design, is part of a more risque category of pocket mirror, metamorphic, that creates a different image when held upside down. The primary view is a woman putting on makeup in a mirror, while the inverted view is a woman's legs.
