I just bought this flask today. I am looking for any information on whether this is a reproduction. I looked up a little, and found some discussion about Clevenger Brothers. Mine is marked CB on the bottom, so I believe that it was reproduced. The front says "Jenny Lind" and the back says "Fislerville Glassworks. Even if it was reproduced, does anyone know possible value, whether it is worth anything at all. Any help is greatly appreciated.
