Vintage 80s or 90s LED ZEPPELIN T-Shirt

Super cool vintage LED ZEPPLIN Tee from either the 80s or 90s based on the limited research I did about the tag. I admittedly don’t know much about vintage band tees, but this one seems to be rare and sought after. I’d love to learn more if anyone has any information about this style. I purchased it from a Salvation Army thrift store about 8 years ago.see pictures for measurements!
