Unique Russian Stacking Doll

This is a unique doll. I bought it from a vendor that was visiting a military base in Germany The vendor told me that this type of doll was generally a hostess gift--a bottle of wine/liquor would be placed inside it. (It would have to be a pretty skinny bottle). She stands approximately 14.5 inches tall and has a signature on the bottom. If you are a collector, then you know that the artist's signature adds value to the piece. (The last 3 dolls pictured are NOT included).
