Butterfly World Map - Four Pieces

"Really? You know the Waterman? Have you seen the 1909 Cahill map it's based - You have a framed reproduction at home?!" Well I have a 3D printed version at home that's even bigger than the first 3D printed Waterman Butterfly World Map Projection. - http://xkcd.com/977/ -

The Waterman Butterfly World Map Projection file cut up into four pieces so that a larger map can be made.
