Circa 1916-1924. This is the first design of what is now known as the contour bottle. It was patented on November 16, 1915 and was referred then as the hobbleskirt bottle. Why hobbleskirt? Well, it looks like the shape of a lady in a skirt and that's one of the things that made this shape so desirable. By 1919 most bottling companies around the country were using this bottle for Coca-Cola.
Now, admittedly this bottle isn't in the best of shape, but it is the only one I have. I got it by luck. This bottle was kicked up by some cows on the farm of my friend, Glen Campbell (not the singer). It may have been buried there for over three-quarters of a century! Sometimes the fun of bottle collecting is the story behind them.
