This is a beautiful and highly collectible antique Mason’s Patent Nov. 30th 1858 fruit jar featuring the distinctive Red Key monogram logo embossed above the main lettering. Measuring approximately 9 inches tall, this half-gallon capacity jar comes in the classic, vibrant light aqua glass color. The embossing is crisp and highly legible across the front of the body, making it an excellent display piece for collectors of historic bottles and farmhouse decor. The jar features a traditional factory ground lip finish typical of mid-to-late nineteenth-century glass manufacturing, showing standard vintage roughness alongside a few minor small chips and flea bites on the inner rim edge as shown in the close-up photos. The glass body contains charming character flaws from production, including a prominent elongated manufacturing air bubble enclosed near the shoulder seam. Please review all the provided images carefully to evaluate the condition, clarity, and overall preservation of this authentic piece of early American utilitarian history. This antique item is being sold strictly as-is with no returns, so please reach out with any questions prior to purchasing.
