I can help with the Penguin edition. Back in the mid-to-late seventies, I found a hardback copy of the same book. Unbelievably, it was being sold as a "remainder" for $1.00. I almost shit my pants when I found it, because even in those days, that was a ridiculously low price for the book - which was in mint condition in dustwrapper. I brought it with me to a signing that Bukowski did (the last signing that he ever did, in fact), at Vinegar Hill in San Pedro. I figured that he might find it interesting to see that book after so many years. He did look surprised to see it. He signed it quickly, then went on to sign the other two books that brought. I remember that he seemed to sign it almost automatically. And it is interesting that my copy has a very similar signature, in the same place.I agree, it seems hard to tell. Attached may help.
That's exactly what mine looks like (sans signature), and what's unsettling about that is the phrase "This selection first published 1969." What that insinuates to me is that "you are holding a more recent printing of a book first published in 1969." Probably just another case of English being more than one language.
