Here are six triangular tiles each of which contains a half sheep, a half guitar, and a half tree. To solve the puzzle arrange the triangles into a hexagon which shows six complete images, two sheep, two guitars, and two trees. I believe there are 30 possible solutions to this puzzle. A solution where the sheep, guitars, and trees, are aligned in three different directions is shown.

The openSCAD program included with Child's Puzzle One, thing:147135, was used to make the tiles.

The tiles are best printed directly on the build platform.

The numerals can be used to create a unique solution. I believe there is only one solution where the sum of the unmatched numbers on the outer triangles is 16. In the example given above the unmatched numbers sum to 13.
