I read a post recently that seemed to suggest that finding original bitters bottles of any type is a feat in and of itself and apparently repros are way more common. I know some basic ways to tell sometimes if a bottle is newer, but how does one tell at a glance if a bitters bottle is a repro or not...what are the biggest signs. I bought one at a yard sale where the lady swore its not a repro(she claimed to be a one time collector), but after reading more, i am not sure if i got taken or not. I only paid $6.50 so it wont kill me either way, but any input is welcome.
