Here is a vintage men shirt, Square Seal brand with a great geometric pattern. This is short sleeve with a notched collar, the collar is quite wide and is 3.5″ long on the ends. It has one chest pocket.
The size is marked as Medium but it’s on the smaller size of medium with a chest measurement of 38″ (96cm). This is new old stock, it was in a packet but was removed to check and photograph, this will be supplied in it’s original packet. We believe this is from the later 70’s or the 80’s based on the style, label and washing instructions.
