Open City No. 80 Nov29-Dec.5, 1968 3 Buk poems / one uncollected

According to David Calonne, between 1967 and 1969 Open City came out 93 times, and Bukowski's column Notes of a Dirty Old Man appeared in 89 of those issues. I wonder how often it happened that the column was called Notes of a Dirty Old Poet, or if this was the only occasion.
