scratch art

Refers to art works created by scratching or engraving a design into a board or other surface that has been prepared by covering with ink, so that the color of the board shows through the scratched design. Colored wax or paint may be applied to create a design on any paper board, or the board may be commercially produced "scratchboard." India ink is often used to cover the wax or paint. A stylus or other sharp instrument is generally used to scratch or scrape away the design.
