A very nice vintage mercury glass fish Christmas tree ornament. Good coloration of silver, aqua and red. Metal cap and loop. Unmarked, probably Poland or Germany, from the later 1940's.
Size is 3-3/4" long. Widest width is 1-1/2" wide.
Condition: only minor few flakes of paint around the head. Some surface rust to the cap. Flaws are marginal so I would consider a nice ornament
