Huge is the operative word here as the largest shade of this lot measures just over 20" in diameter. Clear colorless frosted glass with cut glass decorated foliage and grape clusters. Note pontil to center of shade attesting to its 19th Century vintage. Unmarked ~ Continental or American? Not sure. Secondly, a pair of frosted glass oil lamp shades with ruffled rims and decorated panels. 8 1/4" tall each with a 3 5/8" opening at base. Lastly, a pair of frosted and cut glass oil lamp shades of a much lower profile. Each measures 6 1/4" in diameter by 3" high with a 6" diameter foot ring. All are unmarked. CONDITION: Excellent and undamaged though that's not to say you won't find a ding or flea bite here and there though we found no such dings.
