Led Zeppelin tour shirt. Looks like a bootleg to me. 1977.
Sorry about the quality of the photos on this but it seems that this is as good as the ebay sellers who photographed this shirt could do and the image was too good to pass up. (Also, the shirt at top can be purchased on ebay for $50 if you can fill out a 1987 XL which is probably like a medium by today’s standard. Seems like a reasonable price to me.)
