There was a faint marking on the tag, but it completely disappeared after washing it before listing. I've attached a reference image of the same tag. This is a vintage bowling shirt-style work shirt made by Hilton in the 1970s, made in the USA. Lime green and black two-tone body. Features the Dad's Dog Food company logo. It has details like the open collar style, piping, and side slits of a bowling shirt, but in America during this era, the bowling shirt design was often adopted as a work uniform, and there is a real background of it being distributed as actual workwear. 【Brand】Hilton 【Size】Medium (equivalent to men's S-M) 【Actual Measurements (flat)】 Length: Approximately 75cm Width: Approximately 54cm Shoulder width: Approximately 47cm *Please note that there may be slight variations. 【Country of Origin】Made in USA 【Era】Early 1970s 【Condition】 ・Some stains on the inside of the collar, small stains on the waist (see images) ・Hand-washed once (no spin-drying or ironing).
