On the last entry I discussed Navajo Sammy Smith's small fetish carvings, but he also produces large ones. The Picasso marble and turquoise piece shown here (Ebay item number: 170100339259) is about 1/4 lb in weight and measures 2.5 x 2 inches, a bit bulky for neckwear. I did not think to ask Sammy about his largest fetish creaton ever, but I image it would be at least a 10 pounder or better judging from the size of those I saw yesterday in his workplace.
Native American fetishes never really age, they just grow more influential with time.
