Vintage Matryoshka Babushka Russian Nesting Dolls, 3 Cats and 1 Mouse.

There's some markings on the inside, maybe initials HCS.

Each cat is different and unique. Please look at the photos closely for markings, measurements, and flaws. There's a few minor chips, but it's hard to tell between the design and a chip. There's a residue that I'm nervous to attempt to remove on the large cat at the base.

I'm happy to answer any questions. This is a found treasure not a previously, personally owned item.
