This is an original Vintage Made In USA Nike T-Shirt from 1982.  It is signed by Gaylord Perry and was for his accomplishment of 300 wins.  It says 300 wins is nothing to spit at Seattle 7 New York 3 May 6, 1982.  It will also come with the Gaylord Perry Pamphlet from his night.  These are from my personal collection and acquired by me as original.

17" is the armpit to armpit and 27" is the collar to bottom.
