I love this BIG, beautiful, vintage, signed, United Indian Trader's Association, Navajo, TOADLENA, Sterling Silver and Turquoise, Frog Pin. This is an exceptional, old, Toadlena piece. It is a large 3 inch pin. It is finely detailed and deeply carved. I believe the Center Turquoise piece is Royston Turquoise as it has brown striations. It is marked "UITA" and "22". UITA stands for the United Indian Trader's Association and number 22 is for Toadlena. This vintage pin is in wonderful condition except the clasp is missing the little center piece that holds the pin in. However it forms a "c" clasp and I have worn it like this for many years. This vintage, Navajo beauty is available on my ebay site this week. Starting bid $499.99. Click here to view.
