An Etch A Sketch resembles a thick, flat gray screen in a plastic frame, and is equipped with two knobs on the front of the frame in the lower corners. The knobs move a stylus that displaces Aluminium powder on the back of the screen, leaving a dark line as the stylus is moved. The knobs can thus be used to create lineographic images. One knob moves the stylus horizontally, and the other vertically.
Introduced near the peak of the Baby Boom, the classically simple Etch A Sketch is one of the best-known toys of that generation, and remains popular to this day.
