These bottles came from the same dig as the "imposter" coke hobbleskirt that you'll see a couple of posts down from this one. This site seems to have bottles from the 1880's to the 1930's or so.
Thanks Harry, I didn't think it was a wine bottle, it was too small - but I didn't know what else to label it. Mineral water makes sense. It's a turned-in-mold bottle with some nice seed bubbles. Thanks again.
