Vintage 1950’s Arrow Men’s Shirt

Arrow Perma-Iron Made in Canada. 65% Fortrel Polyester 35% Cotton Size 16-33 Pale mint green in colour. Has a weave like texture. Union made stamp on bag and shirt. There is also a stamp on the shirt that gives washing instructions. Shown in photos. I don’t know if this is long or short sleeved. It doesn’t say on package and I don’t want to take it out of original packaging to find out. A rare find. Unused. In original packaging.
