@Nobleprofessor that shirt could be something great. tbh i dunno that much about shirting, but i'd guess 50s or 60s. the model of shirt is Sawtooth. i think if it were denim or chambray it'd be $$$, but it's super interesting as it is. what is the fiber content? love the pearl snaps! i'd look around the lvc catalog to see if they repro'd this. i assume it's true vintage, but it might help you to research/date to look at the lvc stuff. sweet find.
