A Tsimshian Wood Comb

of classic form, the large rectangular panel very finely carved in relief on each side, with formline designs, representing a bird, perhaps a raven, the downturned beak incised with cross hatching.

For a related example and brief discussion see Phelps, 1976, p. 323 and p. 308: " ...special combs were used for grooming, although they were not worn as ornaments (Drucker, 1955: 90)."

Also see Wardwell, 1996, p. 208, no. 302,  for a comparable in the American Museum of Natural History, New York, 19/448 and Brown, 1998, p. 79, no. 4.21, identified as Haida or Tsimshian: "The design and style of this delicate comb is comparable in formline concepts and relative complexity to that of the large chest panel or bent-corner bowl."
