I have to admit...I thought this was depression glass...until a lovely person with a knowledge of glass told me it was actually opalescent glass of an older age...and its age could be anywhere from 1840 to 1900 or so. Apparently this is Northwood's Klondyke pattern and is rare in this gorgeous green and blue combination. Footed base and a cheery pattern this is a winner for any home! Measures approx. 5" high x 4" in diameter.
