I found a promo from when they introduced the new face:

Apparently there *were* three face types initially, and it said so on some of the official data I've seen (can't remember where, sorry!) which led to the confusion.
For lack of better/official terms, I've just been calling the half-open-eyes mold "fox eyes," after Tsubaki. Interestingly enough, only animal-themed Ai Dolls have this mold.
BTW I'm looking for more official square full-page promo images for some of the early Ai Dolls that don't have them yet (see thumbnails.) It's possible that none exist, but if you happen to have any they'd be welcome (we'll credit you!)
