A highly rare vintage **BIG SMITH** overall from the late 1940s to early 1950s. This piece is in a class of its own compared to current products and mass-produced items from the 1960s onwards, featuring luxurious details unique to the post-war period. The quality of the denim is particularly noteworthy, with the rough, uneven yarn of the time creating a striking **"intense vertical fading"** throughout, exuding an overwhelming aura. 【Rare 40s-50s Early Details Unique to This Item】 ・Black-painted donut buttons: Black lacquer-painted donut buttons, not laurel leaf, following the wartime model of the 1940s. This is a very old specification up to this era. ・Two-tone color bar tacks: Multi-colored bar tacks with red and green threads are used on the V-shaped part of the back. This is a time-consuming design from the early 1950s. ・Two-tone hem chain stitch: The hem has a unique specification with white thread on the inside and black thread on the outside, which was rational at the time. Moreover, it's miraculous that it remains in its **original length (74cm)** without being hemmed. ・Early black tag (with UNION MADE): A vintage tag that symbolizes the 1950s, with a yellow logo on a red frame. ・Decorative stitch pockets: A very old style pocket design with no size notation, only lines (dummy stitches). Actual Size ・Waist: 55cm (Equivalent to W44, a powerful big size) ・Inseam: 74cm (Optimal original length for Japanese body types) ・Hem width: 25cm ・Bib: 30cm ※Please forgive slight errors due to amateur measurements. 【Condition】 The condition is surprisingly good for workwear from over 70 years ago, and above all, the appearance of this "vertical fading" should be irresistible to vintage enthusiasts.
