I've always felt that labels distract from the beauty of the glass, BUT they can provide valuable historical info. that isn't embossed on the glass, eg. proprietor or location the bottle came from. Here are a few locals from my collection. The first is a smelling salts, very hard to find with the stopper.....
This one was found behind a wall in a house in the "'hood" pontiled Corbins Summer Complaint (cholera) Tincture Syracuse NY (note the miss-spelled Corbins on the label)
This is the last one. There is another Fowler bottle, Dr A Fowler's Anti- Epicholic Canton NY. that everyone assumed was from Canton in northern NY. Until I bought this open pontiled, embossed Dr A Fowler Syracuse NY with the label nobody knew what the contents were (extract of wild strawberry) but it also listed Canton NY Onondaga County (near Syracuse) as where it was made. Apparently at one time there were 2 Canton NYs, the one near Syracuse changed to Memphis NY, so both Dr Fowlers bottles are locals.
Here is one that I have . I have some nice labeled whiskies , but they are out in the garage . Too cold out there for me !! I have some small bottles such as these with glass stoppers , not sure where I have out them though . I believe they may have been sample bottles .
