What is that 'Whatsit" - Vintage Tin Decanter

What is the 'whatsit'? Our Sunday revealing of the whatsit was missed due to a very busy weekend, I was unable to sit down at my computer and spend time with Relics and Tales. My apologies to those waiting and waiting for the answer! This little 'whatsit' is a vintage decanter made of tin. It was made in disguise as a book, which was probably hid in the library, and may have contained a dram of very special liquid! Aha! What a wonderful invention and very unique 'whatsit'. It has a wonderful patina which adds to its character and uniqueness.
