Very Rare Atlantic Records 40th anniversary Concert Tee from 1988 MSG!

A very rare and hard to find 40th anniversary concert T-shirt for Atlantic records in 1988 Madison Square Garden. It is extra large and has been sitting in a drawer for 35 years. I may have worn it twice if that. There is slight discoloration under the collar, and under the emblem on front as can be seen in the third and fourth pictures.
