Caitlin at Geo Lounge on pantographs: “Before the use of computers to replicate and manipulate maps, a pantograph was one of the ways used to either reduce or enlarge the size of a map while reproducing an accurate copy of the original map.” I did not know about pantographs—they seem to have been widely used in drawing and diagramming. Maps too, it would seem.
