I believe it originally appeared in The Outsider No. 3, 1962, as part of the "outsider of the year" award Bukowski got. The poem and drawing were part of three (the others were "the priest and the matador" and "old man dead in a room") analyzed by William Corrington. So, is it owned by Linda B. or whoever got The Outsider archives, I dunno.
I could scan those old photocopies if you want.
