help dating Icaros Greek pottery

Hi all,
I have this piece of Icaros pottery made in Rhodes Greece.
All i can guess it is't a napkin holder?
It is about 4" tall x 7" wide. I was thinking mid century, but hoping for some help on this one. also i was reading that the pieces were made with limited numbers and the numbers reflect the amount made and the number of the piece. So is the last number a 1 or a 7?

I read that earlier, But thanks Debora, I missed tha part where they said the ones with gold on the tops were more expensive. This had a lot of gold tpo bottom and all of the painting is outlined in gold paint.Hard to see in the pictures but it is gold leaf?
