I have a cobalt blue flask about 8 inches tall with " Neo-Tono Medicine CO 41 john st new york N.Y". The only pic i have is this blurry one but it gets the point across. Any info or value on the flask!!!! Thanks!!!!!
I dont have a listing for that one. Is it machine made or tooled lip. It looks like maybe turn of the century.
Cobalt is always a good color , may be a good one.
It does look turn-of-the-century. It's probably pretty rare; I've never seen one. In that size, shape, and color, a lot of collectors would probably be interested.
