Mapography: Combined Map Measurer and Magnetic Compass, W/case & instructions.

Description

Fascinating "mapograph" measuring device; this was mapquest before there was such a thing.  Old vintage piece, not sure of year, but charming.  Includes little instructions page, and original leather case.  My grandparents used to use this with paper maps to figure out how many miles it was from point A to point B.
If you collect vintage mapography you'll enjoy this piece.
