Funny the allure that little book still has. I suppose its scarcity makes everyone curious about it. But I will just repeat this:
Blowing My Hero is certainly interesting, but it's a trifle compared to
Charles Bukowski's Scarlet.
Take 20 pages out of
Scarlet - any 20 pages - any you've basically got
Blowing. So if you really want some insight, go with Pam's book.

For the record I just pulled out both versions of
Blowing My Hero again to double check, and while it isn't
un-scannable, strictly speaking, again, you would have to take the book apart to scan it, and even if you did that, the paper is so dark that a proper pdf version would require a bit of Photoshop time and an equal amount of finesse.
If "Amber" wanted to sacrifice one to the scanner gods, it could be done. But I don't think anyone who paid a premium for a copy with the letters is going to tear theirs open to appease the people who want to read it for free.
