Set of 3 Art Glass Bluebird Figurines #2399

Set of 3 bluebirds.  None are marked or have stickers.  I believe the large one was made by Konstglas Sweden.  It is 2.5" tall.  The glass is heavy and very clear.  The 2 smaller birds are the exact same shade of blue and are 1.5" tall.  All in excellent condition, no chips-cracks or scratches.
