Rare Vintage Lacquered Wood Mini Keg Mystery Mug

Here's a super cool piece I call the mystery mug from a desert isle.

It appears to be a beautiful hand-made wooden Mini Keg. I just can't figure out how the thing works.

The inlaid bone is striking, as is the lacquered wood itself. It has some really nice natural patterns in it.

There are a few scuffs in the wood and a skinny crack, all that can easily be repaired.

I have no idea how old it really is. At least 1950's or 60's, possibly older.

Measures 8" high and 9" wide at the spouts.

Great gift!
