Final Countdown 1991 japan tour including Metallica, Thunder, Europe & Tesla

I went to Joe Cocker’s concert in 1988 and got this original t-shirt.It has some spots on it and a couple of small holes toward the bottom and a small rip in the side seam.

Vintage Smith’s Tee

The t’shirt is grey with “Led Zeppelin” in greenish blue and yellow above 4 pictures of each member of the band. The pictures are white bordered in green/blue with the band members logo above each picture in yellow. I have tried to research this tee but I cant find one anywhere. Please see the attached images and please tell me if it could be worth something. Thank You
