These pieces are Ivory (we pretty sure) bone for sure not plastic for sure. They were collected in Africa sixties Two Tusk tips? That are 10 inches by one and three quarters inch. They were “legally acquired prior to February 26, 1976” mean?
February 26, 1976, is the date the African elephant was first listed under CITES (the pre-Convention date). An item that contains African elephant ivory that was removed from the wild prior to February 26, 1976, is considered to be a pre-Convention specimen. This does not mean that the current owner must have purchased or acquired it prior to 1976, but that the item was manufactured from ivory that was taken from the wild prior to 1976. For example, a musical instrument that was manufactured in 1965 using African elephant ivory would be considered a pre-Convention specimen. Likewise, an instrument manufactured in 1985 using ivory acquired by the manufacturer in 1975 would also be considered a pre-Convention specimen. Since it is unlawful to possess specimens that have been traded contrary to CITES or taken in violation of the ESA, the ivory must have been legally acquired.
