A good (meaning cheaper - am I becoming predictable? Ha) alternative to that first edition is the later litmus printing out of Salt Lake City. It has a few letters included that aren't in the original, and Brad Darby photos of Bukowski on the cover rather than the bearded flower child...
That one on e-bay is a litmus edition too, but 1968. Is it the first edition? And, is the one with the buk photos (1975) a 2nd printing of that edition with the letters? Well, which one is the true first? The litmus first or the one I see that is 1968 from Berkeley/Exchange. I have seen one posted also that says both Litmus and Berkeley/Exchange. This is getting downright confusing. Finally, in terms of collectibility, would you rather have a 1968 first, whichever one it is, or a second printing from Litmus signed by Bukowski?
I thought the first 1968 edition (as seen on eBay, with the bearded gas mask cover) was published by Poetry X/Change out of Chicago. But I see someone asked that eBay seller and he says litmus. Krumhansl says Poetry X/Change, Glendale, but on the back of the title page, "a LITMUS first edition," so I guess they are one in the same.
In that case, litmus published all editions of this; the first, as seen on eBay with the bearded gas mask cover, then two later printings of the edition I pictured above, which is from 1975, and states, "First edition with correspondence, second printing."
