I believe this is from the 70s. Green and black check shirts with zippers exist, but button-up versions are not very common. The fabric is as thick as a jacket, so it can be worn as an outer layer. As it is vintage, it is prone to pilling due to the wool, and there are also some threads coming out of the cuffs, so I have marked it as damaged. I don't think it will affect wear. It looks like a box silhouette, but the hem is rounded. From Melton, an American shirt brand, a long-established brand with over 100 years of history, embodying the good old days of "U.S.A. Work Military" American casual style. - Brand: Melton - Color: Green and Black Check - Material: Wool - Style: Shirt Jacket - Made in: USA Kimutaku (Takuya Kimura) Short length Demon Slayer Block check Thank you for viewing.
