I had no idea there was diet soda back in the mid 1950's. I do remember when I was kid in the 1960's the 8 oz. soda bottles. On my last visit to the Silk Mill last month, I went looking for this bottle as I had not seen it before on previous trips. A friend had visited earlier and captured an image of this bottle. I found it in the basement, way back in the shadows in the spare parts shelves off the machine shop area. I made a 30 second exposure and lit it with my small flashlight, using my hand to shape the light.
