Hi everyone,I was planting bulbs in my yard the other day and came across a deeply-buried glass bottle. I dug it out and cleaned it, realized it was an old soda bottle, and decided for the sake of curiosity that I'd try to determine how old it was. The pictures are attached to this post...if they don't show up, I'll try again. It's a clear glass bottle about 9.5 inches tall, seam running along the side all the way up. Several decorative rings around the neck (I believe "embossed" is the term? - it's part of the glass itself, as in part of the mould/cast), "Double Cola" below that, then more decorative rings on the bottle's "shoulders". On the front of the bottle, very faintly (perhaps from an old sticker or something) it says "Double Cola," with the words "Great Drink" above and "A Mighty Flavor" below in a logo, then some even fainter words I can't read (they include the word "flavor"), and at the base is embossed G1332 or C1332. The back of the bottle has very faint writing like the front, and as best as I can read it says: "A real carbonated cola beverage containing the extractive matter of kola nuts and coca leaves (decocainized) blended with natural flavors." Below that, "Double Cola Bottling Co. Nashville, Tenn." At the bottom of the back of the bottle, right above the base, is a tiny raised square. The bottom of the base has the letter "I" inside a circle with a triangle on either side. The number 9 is to the left of this symbol, and to the right and below it are either the number 1 or the letter "I" (I'm thinking it's an "I", since they have periods next to them). Below this, it says "Pat. Applied For Duraglass." I'm happy to take close-up pictures of anything that might be relevant. Thank you in advance for your help!
