That’s not true. Whilst Etsy is not a great resource for the kind of stuff we collect, I’ve bought some very rare, vintage concert memorabilia over the years.
I have a Dylan ticket from Newport 1963 — the only example of its kind ever to surface — signed on the rear by Joan Baez. The autograph is legit, but it’s the historical importance of the ticket itself where the true value lies. And it was a bargain.
