Antique Amber Glass Medicine Bottle Square Body Rolled Lip USA Mark

A charming antique amber glass bottle with a classic square paneled body and a distinctive rolled or flanged lip finish. The rich honey-amber color is deep and clear, typical of early 20th century pharmaceutical and apothecary glassware. The base features an embossed maker's mark showing a triangle logo surrounded by the letters U, S, A and what appears to be additional lettering, consistent with American glass manufacturers of the era. The square corners are gently chamfered, adding visual interest. The interior neck shows some dark residue or mineral deposits visible in close-up photos, and there is light surface grime consistent with age and storage. No chips or cracks are visible. Approximate height is 4 to 5 inches tall based on proportions; please measure before listing. A great piece for bottle collectors, apothecary-style decor, or vintage display.
