Bootlegs are best sold on fan sites of the actual artist. I would find Jethro Tull fan forums and go from there. Back in the day, Elvis Presley bootlegs were popular. Now that RCA has released everything under the son, including many soundboard recordings with their FTD issues, the values have dropped quite a bit.
Selling a very rare album
Want to get your thoughts. I'm selling my album collection and I have a rare issue from Jethro Tull named "Hand in Glove" that only 500 were pressed according to disclogs and popsike. The album actually has paper glued on the front and back with Ian Andersons face with a slogan on the front and the song names on the back. It is a double album in mint condition. How would you determine or who would you ask how much something like this is worth?
