Ivory Elephant

I bought two very cool items at the auction this weekend that I "assume" are Ivory. They sold them as "bone" with a wink of an eye. I think these items are amazing, will post the letter opener seperately. I cannot believe the detail in these carvings. Have no idea of their age and no idea of their value but I think they are cool! Not really sure how to classify these either...figured folk art was appropriate
