This is a tee from the 70's.  It unused and new looking.  It is extremely thin and soft AND VERY STRETCHABLE... ABLE TO FIT MUCH LARGER THAN MEASURED IF YOU PREFER FORM FITTING TEES.  Please check sizes carefully as vintage items are usually smaller.  Shirt is amazing NOS condition. The shirt doesn’t have any stains, odors, or unsightly issues.  Print looks beautiful as pictured.  It has a very rare Healthknit made in USA label, still intact and new looking. The overall size is marked Vintage MEDIUM measuring approximately 17.75” armpit to armpit and 28 inches top to bottom.  UNWASHED AND UNWORN... simply beautiful.  Thank you.
