No date on it. Even so, I think this second shirt is a tad earlier than the white one because of the different tag inside the collar, though not too much since they both have the same style insert. So, 1940s for this shirt?
Vintage shirts aren't my thing and I'm just now getting my hands on some good examples, so if anyone has anything to add (or correct) please do so.
