Yeah, sometimes he's depicted with six legs. . But usually he has eight of them xD I think it depends on the translation, my Norse myth book has him with eight although I've seen others where he only has six.
Insanely good! You know what is my favorite part? It's the golden half circles on top and bottom. They look so 3D, like engraved! Those spirals in the borders look really realistic too. And the ferocious looks on the beasts faces... Cool!
