Vintage 1970s? Men's Knockout Long Sleeve XL Button Placket Shirt. Super Cool!

Description

Here is a very cool shirt, typical of the high fashion casual wear of the late 60's and 70's.  With knit collar and 3 button placket on the chest, the fancy embroidered design is highlighted.  Design is repeated on the long sleeves and at the bottom right.  This is exactly what my stylish Dad would have worn in the late 60s!
The chest front measures 24" from armpit to armpit.
The length from shoulder to hem is 31".
I found it has only one flaw... a teeny tiny hole, very hard to even see, is above the design on the lower right side.  The last of my pictures shows this little hole.
This shirt is a true gem for collectors of fashion memorabilia and history.
