Vintage St. George the Dragon Slayer Dress Shirt 1970's Joel Calif Men's Medium

This is an incredible vintage St. George the Dragon Slayer dress shirt from the 1970's made by Joel California. Size Men's Medium. This was my dad's and he's finally ready to part with it! The dress shirt is sort of sheer. All buttons are accounted for and it is in fantastic condition! My dad says he only wore it a few times. There is no tag to say where it was made or what it is made of. I would say this is a true to size medium. Measurements are approximate: the width from armpit to armpit is 22 in, the sleeve length is 24 in and from the top of the back collar to the bottom of the shirt is almost 30 in.
