Here's a beautiful example of scrimshaw:http://antiquesandthearts.com/Antiques/CoverStory/2010-11-23__15-10-50.html
"This box from the museum's outstanding scrimshaw collection was made between 1840 and 1856 of whale bone and ivory, mahogany, wood and tortoiseshell. It employs hands and stars as decorative motifs. "
"Made of whale ivory and ebony, this crimper is constructed in three pieces to resemble a sea unicorn. All images courtesy New Bedford Whaling Museum."
