If you have to do it yourself anyway, why not make your own projection? I'd do a Dymaxion-style projection onto a truncated icosahedron (Goldberg polyhedron G(1,1), a.k.a. the soccer ball shape), with the poles centered in two of the pentagons, and as many edges as possible over bodies of water. Then I'd print each tile image and plaster it to its own mounting board, trimming the backs of the board edges to 69 degrees on all the hexagons and 73.5 degrees on all the pentagons. At that point, I'd permanently join the tiles with appropriate amounts of contiguous land mass, using brackets, and attach magnets to the remaining edges in such a way that you could assemble them like a puzzle.

I'd rather have a gigantic globe (that can also be dismantled for moving or storage) than have a wall map.
