Having a cameo appearance in a comic is a neat thing if you think about it. It means you've made it in one way or another. Whether in another comic strip or through an internet.
I've appeared in a comic once, back in 2005 in a webcomic called Breakpoint City. That's me with glasses in the 3rd panel.
I used to do webcomics from 2003 to 2005. Let's just say it's best that I don't repost these old strips (I don't even have copies/originals anymore).
But I remember feeling psyched when I appeared in that comic. I know I've made it when I did. Too bad it was due to my crappy comic. Oh well, maybe I'll make a better comic in the future.
