Christine - you were right. This is the reply I received from Essie Zareh:
"This vase is one of our old style avses that were made, I dont know when you have bought this and where, let me know, I can tell you more about it."
I've replied with the pictures of the other piece and ask if she can tell me when and by whom it was made.
You must have a great eye for these things - great call. Thank you!
