Hmmm.... Ivory Detector... These are figurines carved from Russian Mammoth Ivory Tusks imported into and carved in China into Chinese Zodiac Figurines: I am Year of the Boar, my Wife is Year of the Rabbit... At the time, it was perfectly legal for US Citizens to own and transport Mammoth Tusk, as it was NOT an endangered species, rather it is Extinct. I understand NOW you cannot purchase nor transport them into the US. However, these are grandfathered, having been transacted well before the law changes. I purchased these on one of my trips to China. Mammoth Tusk - Russia find China carved Chinese Zodiac BOAR and RABBIT. Estimated age of Mammoth Tusks: 55,000-60,000 BCE.
