You could easily get $250 on eBay or somewhere similar. Even in Pelican Parts classified you'd get a good price.

The first edition unsigned goes for a fair sum. Mine is in about the same condition, although unsigned and I picked it up for around $75 if I remember correctly and at the time that was a good price.

If you do end up selling, and Joe passes, let me know, I'd love to have it for my collection.

Cheers

p.s A bit morbid, but what makes this so rare is that Mark died a couple of weeks after the book was published. So very few were obviously signed.
