That is a bit of a generalization. I'm from the regional area and if I had bottles like those ones I'd be doing backflips. Almost.Yes, Leon they are different. Still if there are variations of the same company and being from a large city I doubt they are rare, but have little demand. Would not say they are worthless just interesting reminders of a long gone company. Pittsburgh collectors I believe in general don't collect these as they are seeking pontil era bottles and colors. Personally I think that is a shame as the history aspect gets overlooked.
