Don't be surprised if, as of 7/6/16, ebay (and/or others) either: (i) changes the rules for listing ivory items (mandating posting of photos of certificates, etc. which demonstrate antique qualification or de minimis exception compliance); or (ii) restricts or bans the sale of all ivory items outright.

That's going to present an issue for me. My dad came back with stuff from the Korean War, and other parts of the world. During his time (pre Korea) as a Merchant Marine. Not exactly a paper trail late 40's early 50's.
