New in Pkg Deadstock c.1971 vtg Men's Lg 16/16.5 Floral/Boho pttrn dress shirt

I took it out of the plastic wrapping for pics, but did not remove pins, cardboard collar shaper. Package graphic has largely rubbed off over 50 yrs, but there are no holes. So this shirt is 50+ years NEW! It is in what I call a Hippy pink & brown floral pattern. The "points" of the collar are 4" long. I am including pic of closest match to collar that Fashion Guild site has. It is labeled " from early 70's shirt ". You may wish to check vintage sizing that may be smaller than today's sizing. I looked up the Duralon Polyester, and I could not find it being used in the clothing industry today. p. It is used now in mechanical bearings.
