Another Christmas bauble from vintage years of the 1930's, a perfect size for a feather tree..  This rather round shape silvered glass ornament features star indents, stained red, around the top half,  The lower half is a zigzag pattern. 

It still retains its metal cap and wire loop for hanging. It is marked JAPAN on the cap. 

Size is 1-1/2"tall x 1-1/2" diameter, at the widest point.   

Condition is good for the age with some spotting.
