I'm almost 67 and played with its predecessor, where you had the sheet against a black slate, drew on it, then lifted the sheet to remove the drawing. I recall first seeing Etch-a-sketch, but was too old to care. Some of my younger relatives had them, though.
I had one of those but I don’t remember it being black slate but some type of black plastic material that was kind of semi soft and the opaque plastic sheet would kind of stick to it and you used a stylus to draw on the plastic sheet. The pressure of the stylus would cause the plastic to stick to the black plastic and show the lines you drew.
