The listing, Arizona Copper Thunderbird Pendant Vintage has ended.
This Thunderbird pendant is vintage and genuine. It comes with a very vintage chain that I am not certain originated with the piece. (My mother had a habit of mixing and matching chains to her vintage pendants, but both are at least 35 years old and probably more.) The Thunderbird is HUGE, at 2.5" in length without the circular chain hole at the top. The chain itself is 14" in circumference, approximately. On the back of the Thunderbird, it says "copper" and something else, but I can't make it out. I added a closeup but my scanner is not the best.
