Who made scratch art?

Scratch art, a technique that involves scratching a dark surface to reveal a lighter color underneath, is believed to have origins in ancient Chinese and Japanese art forms. However, the modern version became popular in the mid-20th century, particularly in the United States, when it was marketed as a craft for children. It was popularized by companies like the American company "Scratch Art," which produced scratchboard kits and materials. The technique has since become a staple in art education and recreational crafting.
