I have spent a long time researching and trying to attribute this vase. I think it may be a Raul Angulo Coronel Vase. The bottom has impressed letters that seem to read ANGU, then maybe some more letters before or after, and then I think I see CORO, and the other side seems to read USA, then a copyright mark, and 618. However, I can't find another like it. Maybe its a collaboration? I just can't figure it out so would love some help!

Approximately 8" H x 8" L x 3" W
