First Mo letter or Mo tract you found strange ?

If my memory serves me it was 1975 and I was embarassed to pass out a tract called Holy Holes.
I was really into winning souls and this tract seemed way off the mark and some people I gave it to made negative commments about it.
There was such a letter right ? With a naked girl on the cover pointing to her holes ?
After that some of the letters starting sounding very bizarre. I think that was the beginning of Mo's openly and public downward slide.
