FROM MADEIRA WITH LOVE...!

Antique molded glass Art Deco pendant lamp shade in a opaque milk white.
 
This is a style of hanging lamp shade that was popular in Portugal and Spain, in the early 20th century.  
 
A round shade was molded with melon ribs.

Sitting on a table, it measures 6 3/4 inches high, approximately 6 3/4 inches in diameter measured across at the widest.

The opening measures 3 inches across.

No cracks or unevenness in the coloration detected.

I found a few flea bites and small chips on the shade rim opening that would be concealed with an adapter.   

I have inserted a standard size playing card in one photo as a reference for size.

MUCH OBLIGED
