Published today, how about that?
This states only ivory from elephants alive pre-1947 is legal.
I have ivory purchased in the South Pacific in 1975 and presumably from China. It could easily come from elephants alive after 1947, yet when I purchased it and brought it into the US, it was legal.
OTOH, one of my smaller pieces is likely not ivory at all, but bone. I see pieces on eBay all the time that resemble my ivory and they all say *bone* and are priced accordingly.
At one time, several years ago, my large, common, carved ivory bridge was selling on eBay for $1500 or more. I believe I paid around $250 for it in 1975. I believe I bought it in Australia.
