Hello. I’m trying to identify a toy from the 60’s. It was a green plastic worm with a light bulb in the nose. There was a phosphor screen it was attached to by a wire; when the nose of the pen was pressed to the screen, one could leave drawings on the screen that could be seen in the dark. I only saw two of these toys when I was a child; both at a goodwill. Anyone know who made this and its name?
Thanks!
