Blenko Glass Turquoise Blue #441-S Doughnut Bottle. This is an early pre-designer design from the 1940's and early 1950's. It is 7 1/4 inches tall and about 5 inches at the widest part. There are no chips, cracks, or water damage, but there is a slight scuff mark at the bottom of the bottle. The bottom has been partially ground and polished, but the pontil mark is rough.
