VINTAGE CERAMIC CO-JOINED DOUBLE TWISTED NECK OIL VINEGAR BOTTLE.  HAS ORIGINAL STOPPERS ON THE ENDS.  BRANDED ON THE BOTTOM WITH THE ORIGINAL GOLD AND BLACK STICKER READING: THAMES JAPAN AND NUMBERED 52/394.
I believe this item is more of a Porcelain material than Ceramic.  It is very heavy and thick so that's why I believe Porcelain.  
The scene on the front is a village street view with very tall houses or buildings on both sides  ... the middle shows a small person... there is a street lamp post between the buildings.   The back shows a tree lined street with a lamp post.  The pour spouts are a twisted neck design with the end pieces being a house shaped ceramic pieces.  They both have their original corks.  One is tight fitting the other a little looser but still fits in the hole and wont fall out.  
There not broken, cracked, chipped, some crazing, etc.  Nice bright vivid images on the front.

Measures 6 inches tall x 5 inches wide x 2 1/4 inches thick.   You are buying a very rare piece
