The back reads federal law forbids sale or reuse of this bottle ;dating it back some time ago 1930s . it has threads. I know some of you cringed at such bottles
If they cringe... let 'em!!! It is a fantastic display piece reminding us of the love and admiration of a sibling. It doesn't get better than that. Makes me wish I'd have had a brother growing up. Cringe away, I think it's priceless. Thanks for sharing.
