Pink Floyd Promotional Only Bootleg

Pink Floyd - Fillmore West (KQED Studios Performance 04-29-1970) . This is the only bootleg record that was released as a promotional copy in 1983, I'd like to know how many of these were made, and how many were made with the promo only label. The album cover art was taken from the Pink Floyd - Atom Heart Mother. This has got to be the rarest bootleg that i have. The only flaw to this record is the discoloration on the left side of the jacket.
