Here is the front cover of <Chessman #1 – The Incredible Adventures of Chessman>, this one has Watson as writer and Christine Hendricks as writer/illustrator (Watson’s girlfriend at the time, and co-resident at the Chess House in Denver).
It also contains <Chessman Battles Birniak!>. The link above gives the issue date as 1975(?).
Next, is the credit page from <Chessman #2 – Treachery in Transylvania! (1982(?))>, the second volume of a series of Chessman Comics done by John L. Watson in the early 1980’s. I had never heard of it, but wonder if the main character featured below is a caricature of Watson himself? It must be…
I found this image on Amazon: http://www.amazon.com/Chessman-Treachery-Transylvania-John-Watson/dp/B0006Y9MFY
They don’t seem to have any copies currently for sale, but I saw that issues sporadically appear for sale on ebay.
You can read more about Watson, written by the man himself, here: http://www.chesspublishing.com/content/6/profile.htm
Christine Hendricks has since died, and a moving testimony to her can be found here: http://www.taom.com/pipermail/brianwall-chesslist/2005-June/000436.html
[Update – Once again, I see that I’m covering material already covered by Edward Winter: see CN #8439 http://www.chesshistory.com/winter/winter113.html
