You are looking at an old school pull down map, that is 54" X 50" by the maker
of Geyer Instructional Aids Co. This is an Expo Graphing Map. It gives the
ability to plot lines, and teach students different ways to show data. #194
195 #196 #197 #198 #199
All maps that have the title "Pull Down Map" is equipped with an original
spring loaded mechanism that works as it should and allows the map to be pulled
down and then retracts back up much like a roller shade window blind. If the
map has the title description "Cloth Map" it will come equipped with a wooden
dowel at the bottom and top of the map and does not retract because it is not
equipped with a spring loaded mechanism.
If you should still have any questions please feel free to ask.
