charles burns BLACK HOLE

pencil on tracing paper, Signed and dated by charles burns on cardstock paper underneath tracing paper, but also signed on tracing paper.
when the black hole hardcover came out, burns went on a signing tour and gave out some of these prelims when you bought a book. these two prelims are both from the same page, where eliza (girl with the tail) first have sex and keith breaks off the tail. i will include a personalized,signed first print BLACK HOLE hardcover with the purchase. recently there was a book of just the prelims for black hole published called ECHO, ECHO. i have not seen a copy, but these should be presented in the book. trades also considered.
