Vintage Northwood Swung Glass Vase Blue Opalescent Aqua 1907 Tree Trunk Antique

Vintage Northwood Swung Glass Vase Blue Opalescent Aqua 1907 Tree Trunk Antique. 9 tall, base is 3 1/4, Top is 4 round. All of the points on top are rounded. One feels a little more pointed than the others, but it doesn't appear to be chipped. Not sure if it was just made that way or not. Cant really tell in the picture. Have to look closely. Very old and beautiful. From my mothers estate.
