Essence of Winter
There has been much discussion here about the BOXES these things come in. It may be an early USG in a Weiser box - and also there is considerable evidence that some newer decks have been put in old boxes by unwitting (or even very naughty, deceitful) sellers. Many people actually don't realise the significance of the box...
Essence of Winter - what EXACTLY is the box like ?
This is the Ebay listing, which shows the front and back of the box:

It looks a lot like the large US Games box with the same font and design etc.
