Someone should give Henry Flint and Adrian Bamforth a nudge as they have both been writer/artists for one pagers.
Not sure if this is for a single person or a team (although someone has just asked over there so we'll know soon enough). I'd be interested in giving it a shot as I have a few single pagers under my belt (all colour and all on the back pages of FQP titles): "No Laughing Matter" (with Steven Denton in Something Wicked #4), "Inseminhate" (with Paul Williams in Something Wicked #5) and "Imaginary Friends" (with Neil Pettitt in FutureQuake #11). I also have a few single page stories in my notes.
