Thanks for the research CanadianBottles never seen them before either. It’s really one of the only reasons I even picked them up to have a look! Was told they came from one of the workers on the bottles! Also got this little press glass ashtray with them.
Wasn't research on that one, it was memory! That ashtray is nice too, looks like an older one based on the logo. I see glass company ashtrays from time to time but don't remember seeing that one before.
