Sketch-a-Graph I still have one in its box. Purchased 1950's I would guess. On the box it states "Made in Australia by Sketch-a-graph Pty. Ltd., PO Box 154, Burwood, N.S.W.
It also states "Scientific drawing teacher for young and old" and "Will enlage, reduce or reproduce original size. For maps, pictures, plans, photographs etc"
My memory is that it produced a very 'wiggly' copy and was very frustrating. Probably why it is still in the box.
