Dear all I ran into a "map" like this in the waitingroom of the stacks of the Scheepvaartmuseum in Amsterdam. So, this is not out in the open. I never saw something like this before. To me, this looks more as if it dates from the 70's/80's. See the pictures.

The Library of Congress describes a 1992 Champion map of Buffalo and Niagara Falls, New York as a wall map designed for use with radial index tape-measure. https://lccn.loc.gov/93685367 Positioning the the tape in specific directions helped people find locations a specific distance from the center/centre. For some, this was easier to use than the alpha-numeric grid system employed by some map companies.

A colleague mentioned that he remembers them in Manchester and they included some kind of roller-pulley system that allowed people to move a selection pointer around on the map. I think the attached photograph might be showing what this kind of map but its not very clear. Its also online at http://www.gmlives.org.uk/imu/request.php?request=Multimedia&method=fetch&key=4869 Any information gratefully received. many thanks Martin Dodge --- Department of Geography University of Manchester Oxford Rd Manchester, M13 9PL UK -- John A.
