Vintage Passport Scotch Blended Scotch Whisky Bottle

This is a vintage square-shaped bottle of Passport Scotch Blended Scotch Whisky, produced by William Longmore & Company Limited. The bottle is constructed from a translucent forest green glass, a signature characteristic of the brand. It features a black screw-top cap that remains sealed with a pink paper tax or revenue stamp, indicating the bottle is likely unopened and dates from the mid-to-late 20th century, potentially the 1970s or 1980s. The front label is primarily black and gold with the 'Passport Scotch' title in a serif font. Below the text, the label includes a vertical row of five colorful heraldic crests in red, light blue, dark green, and yellow, which represent the brand's classic branding. The label also specifies it was imported and bottled by Calvert Distillers Co. in New York. The physical condition appears excellent with no visible chips or cracks in the glass. The paper label shows minor shelf wear but remains legible and intact. The presence of the intact tax stamp is a significant indicator of its vintage status and potential collector value, though some minor evaporation or 'ullage' may be present due to the age of the seal.

I have conducted a visual examination of this vintage Passport Scotch bottle. The item presents as a classic example of mid-to-late 20th-century mass-market blended scotch, likely dating to the early 1970s based on the pink U.S. Internal Revenue tax stamp and the Calvert Distillers Co. import marking. The forest green glass is in excellent condition with no visible chips or fractures. The label exhibits light scuffing consistent with age but retains strong color in the heraldic crests. The presence of the intact tax stamp is the primary driver of value here, as it suggests the contents remain original and unadulterated. From a market perspective, Passport Scotch was a high-volume product rather than a premium single malt, which limits its rarity. While there is a niche market for 'dusty' bottles among scotch enthusiasts who enjoy comparing historical blends to modern iterations, this specific brand does not command high premiums. Value is driven more by its status as a piece of barware Americana than by the liquid's complexity. Limitations: This appraisal is based solely on digital images. Without an in-person inspection, I cannot verify the integrity of the seal (the tax stamp may be brittle or have 'micro-leaks' not visible online). I cannot assess 'ullage' (the fill level) accurately, which significantly impacts the value of vintage spirits. Full authentication would require checking the base of the bottle for glass manufacturer date codes and confirming the absence of adhesive residue around the cap. Consumption is not recommended without a professional assessment of the liquid's clarity and sediment.
