Jack Chang brought this book to our attention: Ingenious Contrivances, Curiously Carved: Scrimshaw in the New Bedford Whaling Museum
A coffee table book detailing 700 of the over 5000 pieces of scrimshaw at the New Bedford Whaling Museum. Beautifully photographed, you can see crimpers, canes, umbrellas, swifts and more all carved to pass the time or sell after their journey was done, or in ports they would stop at to enhance their wages.
Thank you Jack, and thanks to Stuart M. Frank for taking the time
