Without question the most collectible single Bukowski item I've seen or could readilly conjure in my small little brain.
This attitude is how you get roped into paying those astronomical prices for rarities. You think and describe certain books using too many superlatives. Here are some things I've seen:
Flower Fist inscribed to Jane Cooney Baker
Early chaps inscribed to Jon Webb
The same inscribed to John Martin
The Presentation Copy of It Catches inscribed to Lou Webb
Genius of the Crowd inscribed to d.a. levy
ANY ONE of those could EASILY be considered a far more important and superior book to anything that sitting on Pam's shelf (no offense, Pam) or swimming around inside your small little brain. And I'm sure there are many others. $15K for Pam's Scarlet? Feh.
And, unlike you and mjp, I think condition is KING. That copy of Factotum inscribed to Pam looks like it fell out of the trunk of a '66 Rambler when it hit a bump on the Santa Monica Freeway. I wouldn't pay anything for it.
