Henry Amber was an apparel maker based in California, known for its very elaborate craftsmanship and immense popularity at the time. This item was purchased about 20 years ago from a private vintage clothing store. There are some frayed areas on the right front hem of the shirt, as shown in the 4th and 5th photos. There is a stain of about 3 cm, as shown in the 6th photo. It's barely noticeable. I'm not very knowledgeable about vintage clothing, but I think it's a shirt with a good old American atmosphere. The measurements are as follows (approximate): Shoulder width 43cm, body width 40cm, length 70cm, sleeve length 21cm. It's about a men's M to L size for Japanese men.
