This gag is in the latest edition of the Foghorn, the magazine of the Professional Cartoonists' Organisation.
It's used as an example of my work alongside some cartoons by the other Royston and an article I wrote about finding out that there had been another cartoonist with my name (a lady Royston, it turned out). Cartoonists value their unique pen names, so I thought this would be a suitable subject for the mag.
