Big John overalls. Made in Japan vintage from the 70s. Features a SANFORIZED label on the back, predating the BIG WASHING marking. There is no quality label, so I believe this is one of the earliest Big John overalls. The zipper is a Talon semi-automatic. At this time, it may not be Cone Mills denim, but the fabric has a good texture that promises vertical fading. Marked size 30 x 31. Measured flat, waist 39cm, inseam 75cm. A slim silhouette, it fits tightly on a slender person around 170cm tall. It might be better for someone a little shorter or a woman. The hem is chain stitched, but it may have been shortened by about 1 inch. Almost deadstock condition.
