At a local art expo a few weeks ago, I found several Request Comics on display. They included one never-before-seen strip. I took a photo: http://imgur.com/XaMEOCk
Request: "A false comic." - Farren
Panel 1: a photograph of the wall upon which the Request Comics were displayed, mostly empty. "Artomatic time!" "Hm, I should probably put up even more comics than this."
Panel 2: the same wall, filled with more comics.
Panel 3: Ben looks at a spot on the wall. "Oh, but what about that empty area? It really needs something."
Panel 4: "Although, that would mean more work." "Nah, I'll leave that spot blank."
This comic was placed in the empty spot referenced in it.
