Why Lamination:

• It helps protect and preserve the map.

• Lamination enhances the colors on the map.

• The laminated finish can be written on with dry erase markers
  then easily wiped off.

• Laminated maps can be pinned to a wall, but are still flexible
  enough to be shipped in a tube.

• Glass is not needed to frame or mount a laminated map,
  which helps to keep the weight and cost down.
