Each of the twelve enumerated incarnations of the Doctor appear on Robin's 5-inch tall dodecahedron which is charmingly cross stitched in vibrant colors. She writes that the numbers on opposing sides add up to 13, so presumably Peter Davidson is opposite Paul McGann, and so on.
The War Doctor is, I gather, not included. Could one created a 13-sided polyhedron with identical faces? I am not sure. One could certainly do so with non-identical faces. But I was hired to work at Neatorama for my good looks, not my math skills.
