Here’s the Led Zeppelin–er, Zed Leprechaun–picture that started this silliness. Matthew Kriske inked it for me. He is a talented painter and a regular at all the comics-related events and activities here in the Twin Cities. Check out his snazzy new portfolio site and comic Magic Carp, which is a unique blend of cartooning and fine art, with funny references to pop-culture and literature.
So, most people probably know this already, but the joke here is that Robert Plant of Led Zeppelin was way into fantasy back in the 70s. Really. Look at this. So the leprechauns and unicorn take that fixation to a ridiculous extreme.
