4 pieces tetrahedral puzzle with a sticker design of the earth globe.
A modification of the pyraquarter, which is a 1x2x2 transformed into the shape of tetrahedron, with a sticker design of the earth globe. The number of cuts were minimized to maximize the clarity of the earth. One of a whole series of Earth puzzles.
