Likely my most famous chess cartoon, often thought to be Fighting Chess, that appeared on the cover of Chess Life, Pawn Shop has appeared in more publications, and a mono print version from the collection of Larry Christiansen, and my sister in law, Natasha Us Christiansen, hangs at the Boyleston, MA Chess Club in Boston area, over the fireplace. 

I've also used this one in homeless advocacy posters as an illustration for blog.
