These are “Topsy Turvy” Dolls, also known as “Reversible”, “Double”, “Flip”, or “Upside Down” Dolls
My dolls are sad on one side, but give that doll a hug, turn her over, and Voila! she is happy. Each side is dressed in a totally different outfit.
Each image set shows one side, the flip, then the second side of the Topsy Turvy Doll.
