I found a truly special vintage Led Zeppelin t-shirt today when I was browsing the eBay. This Zeppelin shirt was released in 1980/1981 to mark their final tour and as a tribute to John Bonham who died near the end of 1980. Take a closer look at this shirt's graphic here; hover over shirt to zoom in.

The shirt is a four color screen print. Each of the band members are shown on the front but the focus is clearly Bonham in the back, holding his drumstick high. His two bass drums have writing on them. One says "John Bonham", the other says "1948-1980".

This would be a great addition to the official band shirt archive, its currently priced at $250 on eBay.
