This is a highly elaborate artefact traditionally known as Scrimshaw. Scrimshaw is the name given to scrollwork, engravings, and carvings done in bone or ivory. Typically it refers to the handiwork created by whalers made from the byproducts of harvesting marine mammals. It is most commonly made out of the bones and teeth of sperm whales, the baleen of other whales, and the tusks of walruses. It takes the form of elaborate engravings such as pictures and lettering on the surface of the bone or tooth, with the engraving highlighted using a pigment, or, less often, small sculptures made from the same material. However the latter really fall into the categories of ivory carving, for all carved teeth and tusks, or bone carving. The making of scrimshaw began on whaling ships between 1745 to 1759 on the Pacific Ocean, and survived until the ban on commercial whaling. The practice survives as a hobby and as a trade for commercial artisans. On one side of this remarkable object is depicted a naked feminine figure immersed into an uncontaminated landscape: the latter is characterised by a powerful variety of plant species. Above the feminine figure, floral motifs have been engraved. On the other half of the scrimshaw it can be observed a meticulously engraved sailer in all its power and majesty. The able execution of the sea waves undoubtedly represents a peak of scrimshaw miniaturised engraving.
