Probably an early 30's dress/business shirt and at the end of the detachable collar era. Staining all over to different degrees. Looks like it sat in a box way too long. Notice the rectangular lines on the front. The upside is, the fabric has a lot of integrity still. Measures like a large. Study the pictures please, they are an integral part to the description too. Sold as is. Links and collar stud NOT INCLUDED. Questions are welcome.
