There was another drawing thing which would allow one to make a small picture bigger. I can't remember what it was called. It consisted of a framework which connected a stylus, which one would use to trace a picture, to a device held over paper, which had a pencil and which would copy but expand what was being traced.
It was long before computers, of course, and it appealed to me because there were all kinds of photos I liked the idea of painting pictures from. I never got one and never did any of those pictures. It must've been after I'd given up drawing and painting.I remember that. vaguely.
