Here we have a vintage Led Zeppelin 1977 tour shirt. The shirt back also has the Led Zeppelin swan song logo on it. The 1977 tour was really the last big tour for Zeppelin and marked the end of the "biggest band in the world" phase of their career.
This is the kind of shirt I would love to add to the official Band Shirt Archive; my personal collection of vintage shirts I've been collecting for some time now. The front graphics on the front of the shirt are very detailed. The lettering of "Led Zeppelin" is typical of other Led Zeppelin shirts. The graphic below that has a lot going on. People getting off a plane, gangsters waiting in ambush, Jimmy Page on guitar and more. The words at the bottom "In Concert and Beyond" are truly captured in the graphics.
This shirt is currently available on eBay for a cool $450, check out the auction here or just see the graphic here in the archive.
