I've been thinking Josefina would get cubed since April 2018. I found more evidence in October that year, and AG almost proved it in February. But today, when I walked in the American Girl store, I noticed something...

Josefina right by Felicity, Addy and Samantha.

That's it, folks. Josefina is cubed! Well, she has her display still, but I'm pretty sure that the next historical doll will take her place.
