Vintage striped men's shirt

A vintage off-white / brown cotton Jerry Magnin striped shirt. A size 151/2-34 with large French cuffs(needs cuff links), a dagger collar(strong points), and a very thick cotton material, cream background with brown, beige, and orange stripes. There are faint markings or a stamp on the front bottom left and inside the collar, barely visible, possibly a sample ( see photos) . Considering its age, Jerry Magnin ( possibly of I Magnin ?) is the only label/ tag. It is rare, unique, and in very good condition.
