The walrus ivory, whale baleen, or combined ivory and baleen bracelets like this were made to sale to tourists and WW II soldiers stationed in Alaska by Alaskan Eskimos from the 1930's to 1950's. Most were plain but some have etchings (scrimshaw) on the ivory and a few such as this have carved ivory. Here there is a dogsled with driver, and 3 dogs; 2 dogs on one ivory flat "bead"/tile and the single front dog on another. These carvings are very small and the photos are so close up they capture imperfections in the ivory and baleen that can't be seen when looking at this without magnification.
The bracelet is on 2 stretch cords (these likely have been replaced and are not the originals). There are 8 flat baleen beads and 3 carved ivory beads. This has a 9" diameter, beads vary slightly in size but the 4 back baleen beads are roughly 1/2" x 1/2" .. the front 4 baleen beads are roughly 3/4" x 3/4" and the carved ivory beads are roughly 1/2" across and 3/4" long. The baleen beads are about 1/8" deep ... the carvings on the ivory beads extends the depth to about 1/2". Dogs are about 1/2" long, dogsled is about 3/4" long.
PLEASE NOTE: - currently California, New Jersey, New York, New Hampshire, Illinois, and Hawaii, Nevada ban the sale of ALL ivory - so these can not be sold or shipped to anyone in either state. Should you live in one of these states and purchase this - I will not ship to you, I will refund your purchase price.....and relist this item... (And no international sales either - as many countries prohibit purchase/sale of any ivory)
