On the left is an L.G.T.Co. in a brite sky blue and on the right is a Patent / Dec. 19.1871 in a darker aqua. In comparing the two side by side, note the perfectly rounded dome and narrower base on the L.G.T.Co. Both are almost identical height with similar wire groove features. Both are in VVNM condition. I have been wanting to do this comparison for a long time. Many Thanks to Rick Jones who agreed to part with the L.G.T.Co. and make this possible!
