This particular face had me stumped until I got my hands on a doll. It's yet
another new sculpt from the copyright year of 2016, first seen late in 2017,
in the 2018 Fashionistas series. The head is rather blown up as it first
appeared on a Petite Barbie doll body. This sculpt has a big smile with a
molded teeth gap. The Cheerful Check Barbie has painted teeth, but only half
of the opening, so there's room for an even bigger, brighter white smile.
So far (as of January 2018) this is the only doll that has this sculpt, but
I am sure more is to follow. It's getting harder and harder to name the
sculpts. They can't all be called "2016 Barbie" but has to be distinguished
from each other.
