Vintage Men's Dress Shirt~Geometric 1970's~Mens M~EXC! (5-1020)

Description

Thank you so much for looking!
This is a gorgeous very unique shirt!
The shirt has no tags at all.   My husband wears a medium size shirt and it fits him perfectly.  But please do check the measurements that I photographed.
There are 3 letters or initials perhaos on one of the cuffs and in a circle on the back.   Not very visible.
I think my favorite part is on the sleeves.  A different material is used.  If you look, you'll see that it is words.    Seems to be referring to the secret of life and it's challenges.
If I've overlooked any details,  please contact me with any questions.
