I got a reply...
"I appreciate your question.
I know nothing about a serigraph print issued in "Open All Night".
I've looked at this piece and I have most of Bukowski's books, including "Living on Luck" edited by Sean Cooney...on the pictorial inserts after page 138 you'll see a piece created on the same day, May 25th 1965...he seemed to be really into drawing that day. This work at auction now appears to be one of the sketches he drew that day...probably one of the best he did that day in my opinon.
By the way, I'm a professional artist and sculptor, whose work has been shown at the Seattle Art Museum and is currently featured in this months issue of Sculpture Magazine...October 2007, Vol. 26, No. 8 Page 73 & 74...so if you know something I don't know let me know.
My name is Randy Bolander and you can see my sculpture at www.randybolander.com
I'm interseted in your following up on this issue.
Let me know if there is more information that you have.
At this time, I believe that this is a real Bukowski."
