A super-rare Zep t-shirt has been sold at auction for $10,000.

Regarded as one of the rarest and most valuable rock t-shirts in the world, it’s from Led Zeppelin’s 1979 Knebworth House concert series.

Aux.tv reports that the t-short was actually printed as a backstage pass for the shows in very limited edition.

It was originally bought for $123 from the family who owned the printing business that made them.

The vintage t-shirt dealer, Kyle Ermatinger, said, “At the time, I thought I may have overpaid. I got back home, looked it up online and noticed it was ranked #1 as the rarest Zeppelin t-shirt.”

The t-shirt was bought by an Australian bidder, who reportedly bought another rare Zep t-shirt in the same week.
