This is a group of NOS (new old stock, aka deadstock) men's button-up shirts dating from the late 1970s, 1980s and possibly early 90s.
They are mostly longsleeve but as there are random styles and different manufacturers, a few shortsleeve may be in the mix too. Most are poly/cotton. These shirts came out of a NYC clothing store that shut down in the mid-1990s and all the clothing was put into warehouse storage. We bought the entire collection.
Photos are examples only. You may receive any variety of shirt or size including multiples of the same size or colour/style.
