Can you tell me if these sculptures have open or closed contour?

Question

I can't post the link but if you search the name and the numbers it should show up.

Sculpture 1:
Mother and Child
[1979.206.121]

Sculpture 2:
Virgin and Child
[33.23]

Look at the examples there.

I see mother and child as open form, Virgin and child as closed form.

Answer 2

WHAT GROUP WAS THOUGHT TO HAVE MADE THE FIRST MEXICAN SCULPTURES AND WHAT EVIDENCE LED TO THIS BELIEF?
