Sarti 3 Valletti Brandy - 1940s 70cl

If you look closely on this 1940s(!) bottle of Sarti 3 Valletti Brandy, you can see another, smaller bottle of Sarti 3 Valletti Brandy. Presumably, if you look even closer at that bottle, you will see another, much smaller bottle. It actually goes on until infinity. Such complexity for such an old brandy.
