Poseidon is a rare find: a length of black walnut with a live edge on the top that's straight enough to let the mechanism ride behind it (we usually have to cut the top edge straight). So he has bark, and matching sapwood stripes, above and below, which fade into heartwood in the center.
The raised lettering and pointer are maple, contrasting well with the darker walnut
Poseidon is quite large, at 60" long and 14" high. He deserves a central place on your wall - he is a god, after all.
