80s Nike T-shirt. Purchased at a vintage clothing store in Tokyo. There is some discoloration on the front, but I think that adds to the character. Length 66cm, width 50cm, shoulder width 49cm. The following is from Copilot: Oh, this is a valuable tag! This "white background with red letters + red swoosh logo" tag is the type known as the "red tag" or "white x red tag," from the **mid-1980s to the early 1990s**. Estimated era: around 1983-1990 Points to consider based on the features: **White background with red letters + red swoosh logo** → A representative of 1980s NIKE tags. Especially common around 1983-1987. **Size notation "M (38-40)"** → This type of inch notation is often seen on 80s American-made T-shirts, and gradually disappeared after the 90s. **"MADE IN USA" notation** → 80s NIKE products were mainly made in the USA. Manufacturing shifted overseas after the 90s. --------------------- As mentioned above, this is a rare single-stitch, real vintage T-shirt. Please understand that this is a used item. Thank you for looking.
