This mint condition American beehive with 3 patent dates beneath base and IX at top of dome. It is a very pretty light blue with some fizzy champagne bubbles. From this sides view the threads are off center to the left. Would of course be just the opposite from other side. As usual there is barely any threads to speak of except near the bottom where they start at bottom of pin whole. This side displays best being there are fewer stress or annealing cracks coming up from base into the skirt. These annealing cracks are very normal for these old pices. The other side has larger noticable bubbles in the skirt.
