Dieting Goes Retro

Back in the day, Coke came in these cool, curvy, glass bottles. This was before plastic took over the planet. I don't, however, remember there being Diet Coke available in this package. I mean, back then when Coke came in these shapely bottles, had they even invented it yet?I saw this and thought it was too cute to pass by. A vintage (um..yeah) bottle of Diet Coke.
