Old medicine Bottle

Old medicine Bottle - Bottom
Raised O in a square logo

I think this is an old clear medicine bottle, honestly I'm not sure what it was used for. The bottom has the Owens Bottle Company logo of an O in a square. I believe they only used this logo between 1919 and 1929. It has some bubbles and a sloppy mold line. It stands 1-3/4" high and is 3/4" across the bottom. I dug this up in the mid 1970's.
