My copy features a small paper strip with text stapled across the front of the issue reading:
CONTAINING…
Letters from William Burroughs
!!Defending the late Dr. Dent and the apomorphine treatment…
!!Revealing insidious techniques of crap journalism…
!!Showing plainly and bluntly how the cut-up and cross-reading
elements published in My Own Mag are to be understood…
discontented souls who talk about cut-up as ‘a bit of a fad’
please read…right through…twice…

I suspect this issue has it as well, but in the scan it’s folded back to reveal the full cover.

Also, the ‘page 8 insert’ in mine is BLIND, TRAINING…probably from the same textbook as ASTIGMATISM
