I bought the sleeve. The seller was local, met him to pick up the sleeve and chat about his experiences on the Copland project. He confirmed the sleeve was printed in anticipation of the project advancing to the state where it could be pressed to disc, but it never happened... so, the sleeve is about the sum total of all the physical remains of Copland, minus some leaked betas nobody can seem to get working. Still I think this is more than Taligent achieved.
