Amorium was Carlos Oliveira's exchange puzzle for IPP19 in London, 1999.
This 'bird on a barrel' clay jug has no lid and no obvious opening to fill it.
Trying to poor water from it the usual way will make you spill and create a mess.
The puzzle goal is to find out how to fill the jug with water, and then how to drink the water without spiling it.
Shipping determined at close of auction.
