Historically, combs like this are associated with the Haudenosaunee People, (Iroquois). They were made from various materials but they are best known to have been made from moose antler, as is the reproduction example shown. I have never seen two original combs decorated alike, many are decorated with animal and human effigies....little examples of wonderful art in the palm of your hand. And even with the aid of modern tools, it takes me all day to make one.
