This pattern gets confused with Thin Rib and Thin and Wide Rib all the time. This is Northwood's Fine Rib, and the swung vase in green is the hardest to find. This one measures 11 inches tall, has great fiery iridescence, and is free of any damage, chips, cracks! Marked Northwood. We priced it much, much lower than book.
We have the shorter version available as well! See all of the great carnival glass in our shop.
