Here's a nice vintage glass Santa Christmas tree ornament.  The tin cap is marked Japan probably dating around the 1930's.  A pack is swung over Santa's one shoulder laying against his back. A suitable ornament for a feather tree.

Mica flakes edge his cap and bottom of his coat.  His beard is painted as is his eyes. I would consider the condition to be good with only some loss of paint and mica.    

The size of this fellow is 2-7/8" tall, from the bottom to the top of the hook.
