Antique C. Hummeler Hamburg Mineral Water Bottle w/ Porcelain Stopper

A beautiful antique aqua glass mineral water bottle from C. Hummeler's Mineralwasser Anstalt (Mineral Water Establishment) in Hamburg, Germany. The bottle features embossed lettering reading 'C. Hummeler' and 'Hamburg' along with 'Gesetzlich Geschutzt' (legally protected) around the body. The original porcelain bail-top stopper is intact and printed with the company name, a decorative crest, and 'Gesetzlich Geschutzte Mineralwasser Anstalt.' The wire bale hardware is original and shows expected age-related oxidation/rust. The aqua glass displays the characteristic bubbles and imperfections of hand-blown or early mold-blown production, consistent with late 19th to early 20th century manufacture. The base shows a recessed pontil-style kick-up typical of the period. Minor internal residue and light surface grime are visible, consistent with age. No visible chips or cracks in the glass. An attractive piece for collectors of antique bottles, German breweriana, or seltzer and mineral water memorabilia. Approximate height: 9-10 inches based on hand scale in photos.
