Spiegel shirt

I'm going to be honest, I know nothing about this brand or this shirt in particular. I bought it in a large bag of clothing at a rummage sale cause I had thought about using it as a top for a costume. Honestly, the material is kinda itchy to me, so it's just sat in my get rid of pile. Looking up the brand gives me lots of vintage and some not, so I don't know if this would be or if it has any true value so might be a good deal for somebody who knows more about clothes than me lol Tag says size is a 15/16.
